  • PHP template class with variables?

    - by Josh
    I want to make developing on my new projects easier, and I wanted a bare bones very simple template engine solution. I looked around on the net and everything is either too bloated, or makes me cringe. My HTML files will be like so: <html> <head> <title>{PAGE_TITLE}</title> </head> <body> <h1>{PAGE_HEADER}</h1> <p>Some random content that is likely not to be parsed with PHP.</p> </body> </html> Obviously, I want to replace {PAGE_TITLE} and {PAGE_HEADER} with something I set with PHP. Like this: <?php $pageElements = array( '{PAGE_TITLE}' => 'Some random title.', '{PAGE_HEADER}' => 'A page header!' ); ?> And I'd use something like str_replace and load the replaced HTML into a string, then print it to the page? This is what I'm on the path towards doing at the moment... does anyone have any advice or a way I can do this better? Thanks.

  • Shouldn't prepared statements be much more fsater?

    - by silversky
    $s = explode (" ", microtime()); $s = $s[0]+$s[1]; $con = mysqli_connect ('localhost', 'test', 'pass', 'db') or die('Err'); for ($i=0; $i<1000; $i++) { $stmt = $con -> prepare( " SELECT MAX(id) AS max_id , MIN(id) AS min_id FROM tb "); $stmt -> execute(); $stmt->bind_result($M,$m); $stmt->free_result(); $rand = mt_rand( $m , $M ).'<br/>'; $res = $con -> prepare( " SELECT * FROM tb WHERE id >= ? LIMIT 0,1 "); $res -> bind_param("s", $rand); $res -> execute(); $res->free_result(); } $e = explode (" ", microtime()); $e = $e[0]+$e[1]; echo number_format($e-$s, 4, '.', ''); // and: $link = mysql_connect ("localhost", "test", "pass") or die (); mysql_select_db ("db") or die ("Unable to select database".mysql_error()); for ($i=0; $i<1000; $i++) { $range_result = mysql_query( " SELECT MAX(`id`) AS max_id , MIN(`id`) AS min_id FROM tb "); $range_row = mysql_fetch_object( $range_result ); $random = mt_rand( $range_row->min_id , $range_row->max_id ); $result = mysql_query( " SELECT * FROM tb WHERE id >= $random LIMIT 0,1 "); } defenitly prepared statements are much more safer but also every where it says that they are much faster BUT in my test on the above code I have: - 2.45 sec for prepared statements - 5.05 sec for the secon example What do you think I'm doing wrong? Should I use the second solution or I should try to optimize the prep stmt?

  • Session State with MVP and Application Controller patterns

    - by Graham Bunce
    Hi, I've created an MVP (passive view) framework for development and decided to go for an Application Controller pattern to manage the navigation between views. This is targeted at WinForms, ASP.NET and WPF interfaces. Although I'm not 100% convinced that these view technologies really swappable, that's my aim at the moment so my MVP framework is quite lightweight. What I'm struggling to fit in is the concept of a "Business Conversation" that needs state information to be either (a) maintained for the lifetime of the View or, more likely, (b) maintained across several views for the lifetime of a use case (business conversation). I want state management to be part of the framework as I don't want developers to worry about it. All they need to do is to "start" a conversation, "Register" objects and the framework does the rest until the "end" a conversation. Has anybody got any thoughts (patterns) to how to fit this into MVP? I was thinking it may be part of the Application Controller responsibility (delegating to a Conversation Manager object) as it knows about current state in order to send the user to the next view.... but then I thought it may be up to the Presenter to start and end the conversation so then it comes down the presenters to manage conversations and the objects registered for the that conversation. Unfortunately that means presenters can't be used in different conversations... so that idea doesn't seem right. As you can see, I don't think there is an easy answer (and I've looked for a while). So anybody else got any thoughts?

  • Debugging StoreKit functionality without a device

    - by Rolf Staflin
    Hi! I'm porting an app with in-app purchase functionality from the iPhone to the iPad, but the simulator doesn't handle any StoreKit calls (they fail immediately with a warning). Since there are no iPads available yet, I can't use a device for debugging. I have thought of a few alternatives: Use the iPhone code as is. This is the safe bet since everything already works on the iPhone, but it will not feel right on the iPad (there are several ViewControllers in a NavigationController involved on the iPhone, but everything could fit on one screen on the pad). Write a test framework for StoreKit. I actually started doing this, but I won't be able to finish it in time. Submit untested code and pray. Nah, just kidding -- that's not an option :) So, any thoughts? Has anyone else written a test framework for this kind of thing? I googled a bit but couldn't find anything. I'm grateful for any thoughts on this!

  • SQL Server database with clustered GUID PKs - switch clustered index or switch to sequential (comb)

    - by Eyvind
    We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs). So, it seems there are basically two options here (short of throwing out GUIDs as PKs altogether, which we cannot do (at least not at this time)). We could change the GUID generation algorithm to e.g. the one that NHibernate uses, as detailed in this post, or we could, for the tables that are under the heaviest use, change to a different clustered index, e.g. an IDENTITY column, and keep the "random" GUIDs as PKs. Is it possible to give any general recommendations in such a scenario? The application in question has 500+ tables, the largest one presently at about 1,5 million rows, a few tables around 500 000 rows, and the rest significantly lower (most of them well below 10K). Furthermore, the application is installed at several customer sites already, so we have to take any possible negative effects for existing customer into consideration. Thanks!

  • what can be causes of http server crash?

    - by mithunmo
    Hello , I am using WAMP server on Windows XP. - Apache 2.2.11 - MySQL 5.1.36 (INNODB engine) - PHP 5.3.0 I observe that my WAMP server crashes in the following scenarios 1) IF I use a Low end PC ( low processor speed and low RAM) 2) After making some changes to httpd.conf file .For eg changing the Allow from IP address . But here it crashes only once and then it starts to work fine. 3) Random crashes CRASH LOG szAppName : httpd.exe szAppVer : 2.2.11.0 szModName : php5ts.dll szModVer : 5.3.0.0 offset : 0000c309 C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\httpd.exe.mdmp C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\appcompat.txt My questions 1) Does high CPU utilization/LOW RAM can also cause the HTTP server to crash ? 2) excessive file reading as in every 10 seconds ? 3) unlimited script execution time . I have set the maximum execution time in php script to 0 as my script has to execute for sometimes 2-3 days. Is there any way to avoid this ? 4) Access to Database ? Should we use lock before reading and writing Can these be the reasons for random wamp server crashes ? OR is is some other programming error ? Please guide me . Regards, Mithun

  • Double buffering with C# has negative effect

    - by Roland Illig
    I have written the following simple program, which draws lines on the screen every 100 milliseconds (triggered by timer1). I noticed that the drawing flickers a bit (that is, the window is not always completely blue, but some gray shines through). So my idea was to use double-buffering. But when I did that, it made things even worse. Now the screen was almost always gray, and only occasionally did the blue color come through (demonstrated by timer2, switching the DoubleBuffered property every 2000 milliseconds). What could be an explanation for this? using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Paint(object sender, PaintEventArgs e) { Graphics g = CreateGraphics(); Pen pen = new Pen(Color.Blue, 1.0f); Random rnd = new Random(); for (int i = 0; i < Height; i++) g.DrawLine(pen, 0, i, Width, i); } // every 100 ms private void timer1_Tick(object sender, EventArgs e) { Invalidate(); } // every 2000 ms private void timer2_Tick(object sender, EventArgs e) { DoubleBuffered = !DoubleBuffered; this.Text = DoubleBuffered ? "yes" : "no"; } } }

  • No long-running conversations - IllegalArgumentException: Stack must not be null

    - by Markos Fragkakis
    Hi all, I have a very simple application with just 2 pages on WebLogic 10.3.2 (11g), Seam 2.2.0.GA. I have a command button in each, which makes a redirect-after-post to the other. This works well, as I see the URL of the current page I am seeing in the address bar. BUT, even though I have no long-running conversations defined, after a random number of clicks, and - I think - after a random number of seconds (~10s - 60s) I get the lovely exception at the end of this post. Now, if I have understood how temporary conversations work when redirecting this happens: When I first see my application, the url is http://localhost:7001/myapp When I click the button in pageA.xhtml, I end up in "pageB.xhtml?cid=26". This is normal because Seam extends the temporary conversation of the first request to last until the renderResponse phase of the redirect. So, it uses the cid (Conversation Id) of the extended temporary conversation to find any propagated parameters. When I click the button in pageB.xhtml, I end up in pageA.xhtml?cid=26 The same cid was given to the new extended temporary conversation. This is normal because the conversation ended at the end of the previous redirect-after-post, and not the number 26 is free to use as a cid. Is this all correct? If yes, why does this happen: If I re-type the applications home address (showing pageA) and re-click, I end up in pageB.xhtml?cid=29, which is a different number than 26. But 26 has ended after the previous RenderResponse phase, befire I re-types the url. Why is it not used instead of 29? So, to sup up, 2 questions: Why do I get the exception, even though I have not started any long-running conversations? What happens exactly with the cid? On what basis does it change? Cheers,

  • Adding AJAX call to function triggered popup blocker

    - by jerrygarciuh
    Hi folks, I have a client who wants to open variously sized images in a centered popup. I tried to get them to use FancyBox but they don't want interstitial presentation, so... I initially was opening a generic popup which resized and centered onload based on image size but they don't like the shift so I added a PHP script to echo the sizes and used jQuery to fetch the size info to feed into the pop up call. But it appears the delay this causes is setting off all popup blockers. Here is the JS $("#portfolioBigPic").click(function () { var src = $("#portfolioBigPic").attr('src'); var ar = src.split('/'); var fname = ar.pop(); fname = '/g/portfolio/clients/big/' + fname; $.get("imgsize.php", { i: fname}, function(data){ var dim = data.split(","); popit(fname,dim[0],dim[1]); }); }); function popit(img,w,h) { var features = 'width='+w+',height='+h+', toolbar=0, location=0, directories=0, status=0, menubar=0, scrollbars=0, resizable=1,'; var left = (screen.width/2)-(w/2); var top = 0; features += 'top='+top+',left='+left; bigpic = window.open('portfolioBigPic.php?img='+img, 'bigpic',features); bigpic.focus(); } The only difference between dodging the blockers and failing is that I added the AJAX .get and use it to specify w and h. Any thoughts on how to avoid this? Maybe I should use PHP to get widths and heights of all the big pics and write a JS array of them when this page loads? Am I right that the delay caused by fetching the data is tripping the blockers? Thoughts? Any advice much appreciated. JG

  • Majordomo/Mailman - Yahoo/Google Groups

    - by tom smith
    Hi. Not an app question, but thought that I might ask here anyway! The responses might help someone. I've got an app where we're going to be dealing with 5000-10000 people in a group/pool. Periodically, different subsets of people will break off in their own group. I'm looking for thoughts on how to manage/approach this situation. (For now, all of this is being managed on a few servers in the garage, with dynamic IP) I've looked into the Yahoo/google groups, and they seem to be reasonable. The primary issue that I see with this approach, is that I don't have a good way of quickly/easily alowing a subset of the group to form their own group for a given project. This kind of function is critical. The upside to this though, I wouldn't have to really set anything up. And the hosted groups could send emails to the user all day along, without running into cap/bandwidth limits The other approach is a managed list, like mailman/majordomo. This approach appears to be more flexible, and looks like ti could be modified to handle the quick creation of lists, allowing users to quickly be assigned to different lists on the fly.. The downside, I'd have to run my own Mailman/Majordomo instance, as well as the associated mail server. Or I could look at possibly using one of the hosted service.. But this is for a project on the cheap, so we're really trying to keep costs down. Thoughts/Comments/Pointers would be greatly appreciated. Thanks in advance -tom

  • Need a regular expression to parse a text body

    - by Ali
    Hi guys, I need a regular expression to parse a body of text. Basically assume this that we have text files and each of which contains random text but within the text there would be lines in the following formats - basically they are a format for denoting flight legs. eg: 13FEB2009 BDR7402 1000 UUBB 1020 UUWW FLT This line of text is always on one line The first word is a date in the format DDMMMYYYY Second word could be of any length and hold alphanumeric characters third word is the time in format HHMM - its always numeric fourth word is a location code - its almost always just alphabets but could also be alphanumeric fifth word is the arrival time in format HHMM - its always numeric sixth word is a location code - its almost always just alphabets but could also be alphanumeric Any words which follow on the same line are just definitions A text file may contain among lots of random text information one or more such lines of text. I need a way to be able to extract all this information i.e just these lines within a text file and store them with their integral parts separated as mentioned in an associative array so I have something like this: array('0'=>array('date'=>'', 'time-dept'=>'', 'flightcode'=>'',....)) I'm assuming regular expressions would be in order here. I'm using php for this - would appreciate the help guys :)

  • Numpy: Sorting a multidimensional array by a multidimensional array

    - by JD Long
    Forgive me if this is redundant or super basic. I'm coming to Python/Numpy from R and having a hard time flipping things around in my head. I have a n dimensional array which I want to sort using another n dimensional array of index values. I know I could wrap this in a loop but it seems like there should be a really concise Numpyonic way of beating this into submission. Here's my example code to set up the problem where n=2: a1 = random.standard_normal(size=[2,5]) index = array([[0,1,2,4,3] , [0,1,2,3,4] ]) so now I have a 2 x 5 array of random numbers and a 2 x 5 index. I've read the help for take() about 10 times now but my brain is not groking it, obviously. I thought this might get me there: take(a1, index) array([[ 0.29589188, -0.71279375, -0.18154864, -1.12184984, 0.25698875], [ 0.29589188, -0.71279375, -0.18154864, 0.25698875, -1.12184984]]) but that's clearly reordering only the first element (I presume because of flattening). Any tips on how I get from where I am to a solution that sorts element 0 of a1 by element 0 of the index ... element n?

  • Silverlight HttpWebRequest.Create hangs inside async block

    - by jack2010
    I am trying to prototype a Rpc Call to a JBOSS webserver from Silverlight (4). I have written the code and it is working in a console application - so I know that Jboss is responding to the web request. Porting it to silverlight 4, is causing issues: let uri = new Uri(queryUrl) // this is the line that hangs let request : HttpWebRequest = downcast WebRequest.Create(uri) request.Method <- httpMethod; request.ContentType <- contentType It may be a sandbox issue, as my silverlight is being served off of my file system and the Uri is a reference to the localhost - though I am not even getting an exception. Thoughts? Thx UPDATE 1 I created a new project and ported my code over and now it is working; something must be unstable w/ regard to the F# Silverlight integration still. Still would appreciate thoughts on debugging the "hanging" web create in the old model... UPDATE 2 let uri = Uri("http://localhost./portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // this WebRequest.Create works fine let req : HttpWebRequest = downcast WebRequest.Create(uri) let Login = async { let uri = new Uri("http://localhost/portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // code hangs on this WebRequest.Create let request : HttpWebRequest = downcast WebRequest.Create(uri) return request } Login |> Async.RunSynchronously I must be missing something; the Async block works fine in the console app - is it not allowed in the Silverlight App?

  • Assigning static final int in a JUnit (4.8.1) test suite

    - by Dr. Monkey
    I have a JUnit test class in which I have several static final ints that can be redefined at the top of the tester code to allow some variation in the test values. I have logic in my @BeforeClass method to ensure that the developer has entered values that won't break my tests. I would like to improve variation further by allowing these ints to be set to (sensible) random values in the @BeforeClass method if the developer sets a boolean useRandomValues = true;. I could simply remove the final keyword to allow the random values to overwrite the initialisation values, but I have final there to ensure that these values are not inadvertently changed, as some tests rely on the consistency of these values. Can I use a constructor in a JUnit test class? Eclipse starts putting red underlines everywhere if I try to make my @BeforeClass into a constructor for the test class, and making a separate constructor doesn't seem to allow assignment to these variables (even if I leave them unassigned at their declaration); Is there another way to ensure that any attempt to change these variables after the @BeforeClass method will result in a compile-time error? Can I make something final after it has been initialised?

  • Delphi 2010 - Source files randomly become read-only in editor?

    - by Justin
    Does anyone else have this problem or is my Delphi cursed somehow? I'll have a bunch of forms and files open in tabs in the editor and I'll be typing away and then suddenly everything stops - my .pas file has, seemingly at random, become read-only. Sometimes I can just right-click the tab at the top and uncheck "Read-Only" and continue, but sometimes this option is checked and greyed-out (disabled), meaning I can't uncheck it and I can't make any further edits to the file. This too seems to be random. In the latter case, the only solution is to save the file in question, which works, despite Delphi's assertion that the file is read-only, close its tab in the editor, and re-open it. Not catastrophic, really, but it's starting to become annoying. Could it be that I am hitting a keyboard command combination accidentally to do this or is this a bug in Delphi? I'm in Delphi 2010, Windows 7. Doubt it's anything to do with installed packages, but if anyone wants the list I'll generate it and attach it here.

  • Machine Learning Algorithm for Predicting Order of Events?

    - by user213060
    Simple machine learning question. Probably numerous ways to solve this: There is an infinite stream of 4 possible events: 'event_1', 'event_2', 'event_4', 'event_4' The events do not come in in completely random order. We will assume that there are some complex patterns to the order that most events come in, and the rest of the events are just random. We do not know the patterns ahead of time though. After each event is received, I want to predict what the next event will be based on the order that events have come in in the past. The predictor will then be told what the next event actually was: Predictor=new_predictor() prev_event=False while True: event=get_event() if prev_event is not False: Predictor.last_event_was(prev_event) predicted_event=Predictor.predict_next_event(event) The question arises of how long of a history that the predictor should maintain, since maintaining infinite history will not be possible. I'll leave this up to you to answer. The answer can't be infinte though for practicality. So I believe that the predictions will have to be done with some kind of rolling history. Adding a new event and expiring an old event should therefore be rather efficient, and not require rebuilding the entire predictor model, for example. Specific code, instead of research papers, would add for me immense value to your responses. Python or C libraries are nice, but anything will do. Thanks! Update: And what if more than one event can happen simultaneously on each round. Does that change the solution?

  • Use jquery to create a multidimensional array

  • Validation in n-tier asp.net mvc applications

    - by sTodorov
    Dear Stack Overflow gurus, I am looking for some practical/theoretical information regarding best practices for validation in asp.net mvc n-tier applications. I am working on a .Net application divided into the following layers: UI - Mvc3 BLL layer - all business rules. Decoupled from data access and UI layers through interfaces DAL layer - Data access with the repository pattern, EF4 and pocos Now, I am looking for a nice, clean and transparent way to specify my validation rules. Here are some thoughts on the matter so far: UI validation should only be responsible for user input and its validity. BLL validation should be handling the validity of the data regarding the application business rules. My main concern is how to bind the BLL and UI validation in the most efficient way. One think I am would like to avoid is having the UI check in a collection of validation and adding manually errors to the ModelState. Furthermore, I do not want to pass the ModelState to the BLL to be populated in there. I will appreciate any thoughts on the matter. P.S. Should this question be marked as a discussion ?

  • The IOC "child" container / Service Locator

    - by Mystagogue
    DISCLAIMER: I know there is debate between DI and service locator patterns. I have a question that is intended to avoid the debate. This question is for the service locator fans, who happen to think like Fowler "DI...is hard to understand...on the whole I prefer to avoid it unless I need it." For the purposes of my question, I must avoid DI (reasons intentionally not given), so I'm not trying to spark a debate unrelated to my question. QUESTION: The only issue I might see with keeping my IOC container in a singleton (remember my disclaimer above), is with the use of child containers. Presumably the child containers would not themselves be singletons. At first I thought that poses a real problem. But as I thought about it, I began to think that is precisely the behavior I want (the child containers are not singletons, and can be Disposed() at will). Then my thoughts went further into a philosophical realm. Because I'm a service locator fan, I'm wondering just how necessary the notion of a child container is in the first place. In a small set of cases where I've seen the usefulness, it has either been to satisfy DI (which I'm mostly avoiding anyway), or the issue was solvable without recourse to the IOC container. My thoughts were partly inspired by the IServiceLocator interface which doesn't even bother to list a "GetChildContainer" method. So my question is just that: if you are a service locator fan, have you found that child containers are usually moot? Otherwise, when have they been essential? extra credit: If there are other philosophical issues with service locator in a singleton (aside from those posed by DI advocates), what are they?

  • Why does Fabric display the disconnect from server message for almost 2 minutes?

    - by Matthew Rankin
    Fabric displays Disconnecting from username@server... done. for almost 2 minutes prior to showing a new command prompt whenever I issue a fab command. This problem exists when using Fabric commands issued to both an internal server and a Rackspace cloud server. Below I've included the auth.log from the server, and I didn't see anything in the logs on my MacBook. Any thoughts as to what the problem is? Server's SSH auth.log with LogLevel VERBOSE Apr 21 13:30:52 qsandbox01 sshd[19503]: Accepted password for mrankin from 10.10.100.106 port 52854 ssh2 Apr 21 13:30:52 qsandbox01 sshd[19503]: pam_unix(sshd:session): session opened for user mrankin by (uid=0) Apr 21 13:30:52 qsandbox01 sudo: mrankin : TTY=unknown ; PWD=/home/mrankin ; USER=root ; COMMAND=/bin/bash -l -c apache2ctl graceful Apr 21 13:30:53 qsandbox01 sshd[19503]: pam_unix(sshd:session): session closed for user mrankin Server Configuration OS: Ubuntu 9.10 OpenSSH: Ubuntu package version 1.5.1p1-6ubuntu2 Client Configuration OS: Mac OS X 10.6.3 Fabric ver 0.9 Vritualenv ver 1.4.7 pip ver 0.7 Thoughts on Cause of the Issue I don't know how long the problem has existed. However, I know that at one point I didn't have this problem. Things that have changed since then are that I have recreated my virtualenv's using virtualenv 1.4.7, virtualenvwrapper 2.1, and pip 0.7. Not sure if this is related, but it is a thought since I run my fabfiles from within a virtualenv.

  • Trouble with C# array

    - by Biosci3c
    Hi, I am writing a card playing program as a way of learning C#. I ran into an issue with an array going out of bounds. Here is my code: namespace Pcardconsole { class Deck { public Deck() { // Assign standard deck to new deck object int j; for (int i = 0; i != CurrentDeck.Length; i++) { CurrentDeck[i] = originalCards[i]; } // Fisher-Yates Shuffling Algorithim Random rnd = new Random(); for (int k = CurrentDeck.Length - 1; k >= 0; k++) { int r = rnd.Next(0, k + 1); int tmp = CurrentDeck[k]; CurrentDeck[k] = CurrentDeck[r]; CurrentDeck[r] = tmp; // Console.WriteLine(i); } } public void Shuffle() { // TODO } // public int[] ReturnCards() // { // TODO // } public int[] originalCards = new int[54] { 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D, 0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, 0x28, 0x29, 0x2A, 0x2B, 0x2C, 0x2D, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x3A, 0x3B, 0x3C, 0x3D, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4A, 0x4B, 0x4C, 0x4D, 0x50, 0x51 }; public int[] CurrentDeck = new int[54]; } class Program { static void Main(string[] args) { // Create a Deck object Deck mainDeck = new Deck(); Console.WriteLine("Here is the card array:"); for (int index = 0; index != mainDeck.CurrentDeck.Length; index++) { string card = mainDeck.CurrentDeck[index].ToString("x"); Console.WriteLine("0x" + card); } } } The hexidecimal numbers stand for different cards. When I compile it I get an array index out of bounds error, and a crash. I don't understand what is wrong. Any help would be much appreciated.

  • Shouldn't prepared statements be much faster?

    - by silversky
    $s = explode (" ", microtime()); $s = $s[0]+$s[1]; $con = mysqli_connect ('localhost', 'test', 'pass', 'db') or die('Err'); for ($i=0; $i<1000; $i++) { $stmt = $con -> prepare( " SELECT MAX(id) AS max_id , MIN(id) AS min_id FROM tb "); $stmt -> execute(); $stmt->bind_result($M,$m); $stmt->free_result(); $rand = mt_rand( $m , $M ).'<br/>'; $res = $con -> prepare( " SELECT * FROM tb WHERE id >= ? LIMIT 0,1 "); $res -> bind_param("s", $rand); $res -> execute(); $res->free_result(); } $e = explode (" ", microtime()); $e = $e[0]+$e[1]; echo number_format($e-$s, 4, '.', ''); // and: $link = mysql_connect ("localhost", "test", "pass") or die (); mysql_select_db ("db") or die ("Unable to select database".mysql_error()); for ($i=0; $i<1000; $i++) { $range_result = mysql_query( " SELECT MAX(`id`) AS max_id , MIN(`id`) AS min_id FROM tb "); $range_row = mysql_fetch_object( $range_result ); $random = mt_rand( $range_row->min_id , $range_row->max_id ); $result = mysql_query( " SELECT * FROM tb WHERE id >= $random LIMIT 0,1 "); } defenitly prepared statements are much more safer but also every where it says that they are much faster BUT in my test on the above code I have: - 2.45 sec for prepared statements - 5.05 sec for the secon example What do you think I'm doing wrong? Should I use the second solution or I should try to optimize the prep stmt?

  • Rot13 for numbers.

    - by dreeves
    EDIT: Now a Major Motion Blog Post at http://messymatters.com/sealedbids The idea of rot13 is to obscure text, for example to prevent spoilers. It's not meant to be cryptographically secure but to simply make sure that only people who are sure they want to read it will read it. I'd like to do something similar for numbers, for an application involving sealed bids. Roughly I want to send someone my number and trust them to pick their own number, uninfluenced by mine, but then they should be able to reveal mine (purely client-side) when they're ready. They should not require further input from me or any third party. (Added: Note the assumption that the recipient is being trusted not to cheat.) It's not as simple as rot13 because certain numbers, like 1 and 2, will recur often enough that you might remember that, say, 34.2 is really 1. Here's what I'm looking for specifically: A function seal() that maps a real number to a real number (or a string). It should not be deterministic -- seal(7) should not map to the same thing every time. But the corresponding function unseal() should be deterministic -- unseal(seal(x)) should equal x for all x. I don't want seal or unseal to call any webservices or even get the system time (because I don't want to assume synchronized clocks). (Added: It's fine to assume that all bids will be less than some maximum, known to everyone, say a million.) Sanity check: > seal(7) 482.2382 # some random-seeming number or string. > seal(7) 71.9217 # a completely different random-seeming number or string. > unseal(seal(7)) 7 # we always recover the original number by unsealing.
