  • PHP bitwise left shifting 32 spaces problem and bad results with large numbers arithmetic operations

    - by Victor Stanciu
    Hello, I have the following problems: First: I am trying to do a 32-spaces bitwise left shift on a large number, and for some reason the number is always returned as-is. For example: echo(516103988<<32); // echoes 516103988 Because shifting the bits to the left one space is the equivalent of multiplying by 2, i tried multiplying the number by 2^32, and it works, it returns 2216649749795176448. Second: I have to add 9379 to the number from the above point: printf('%0.0f', 2216649749795176448 + 9379); // prints 2216649749795185920 Should print: 2216649749795185827

  • PHP Session variables not passing across pages

    - by mitch
    Common problem, but I'm stumped. Session variables are passing across pages on my local (localhost) deployment, but not on my (www) host. I use a common includes file for each page with this code: $sessionDomain = "/"; @ini_set("session.cookie_path",$sessionDomain); $sessionName = "ccSID".md5('/store/'); session_name($sessionName); session_start(); I confirmed that the session ID cookie (ccSIDxxxxx...) remains the same across pages in my browser, but session variables don't seem to hold up when changing to a page in a different directory.

  • Help with PHP recursive navigation list menu

    - by Jason
    Hi all, I am trying to add a dynamic recursive navigation list menu to a site of am working on. The scenerio is that the menu has 2 levels related by a parentid(preid). My issue is that I can display the 1st level list correctly, however I cannot get the second level to display properly. I am not sure where to add the UL and /UL tags for the second level. This is what I am after <ul> <li>Item 1</li> <li>item 2</li> <li>item 3</li> <ul> <li>sub item 1</li> <li>sub item 2</li> </ul> <li>Item 4</li> <li>item 5</li> <ul> <li>sub item 1</li> <li>sub item 2</li> </ul> <li>item 6</li> </ul> This is actually what i am getting with the below code: <ul> <li>item 1 <ul> </ul> </li> <li>item 2 <ul> <li>sub item 1</li> <ul> </ul> <li>sub item 2</li> <ul> </ul> </ul> </li> <li>Sports Injuries <ul> </ul> </li> </ul> </li> </ul> Below is the class file I am using to create the menu: class Dynamic_Menu { function getConfig() { $this->DB_SERVER = 'localhost'; $this->DB_USER = '***'; $this->DB_PASS = '***'; $this->DB_NAME = '***'; } function __construct() { $this->getConfig(); $Conn = mysql_connect($this->DB_SERVER, $this->DB_USER, $this->DB_PASS); if (!$Conn) die("Error: ".mysql_errno($Conn).":- ".mysql_error($Conn)); $DB_select = mysql_select_db($this->DB_NAME, $Conn); if (!$DB_select) die("Error: ".mysql_errno($Conn).":- ".mysql_error($Conn)); } function select_row($sql) { //echo $sql .

I have been banging my head with this for the last 2 days. Any help would be greatly appreciated, thanks...

  • Mark duplicates in MySql with php (without deleting)

    - by Adam
    So, I'm having some problems with a MySQL query (see other question), and decided to try a different approach. I have a database table with some duplicate rows, which I actually might need for future reference, so I don't want to remove. What I'm looking for is a way to display the data without those duplicates, but without removing them. I can't use a simple select query (as described in the other question). So what I need to do is write a code that does the following: 1. Go through my db Table. 2. Spot duplicates in the "ip" column. 3. Mark the first instance of each duplicate with "0" (in a column named "duplicate") and the rest with "1". This way I can later SELECT only the rows WHERE duplicate=0. NOTE: If your solution is related to the SELECT query, please read this other question first - there's a reason I'm not just using GROUP BY / DISTINCT. Thanks in advance.

  • Call a protected method from outside a class in PHP

    - by Chad Johnson
    I have a very special case in which I need to call a protected method from outside a class. I am very conscious about what I do programmingwise, but I would not be entirely opposed to doing so in this one special case I have. In all other cases, I need to continue disallowing access to the internal method, and so I would like to keep the method protected. What are some elegant ways to access a protected method outside of a class? So far, I've found this. I suppose it may be possible create some kind of double-agent instance of the target class that would sneakily provide access to the internals...

  • Google App Engine - "Invalid sender format" when sending e-mail

    - by Taylor Leese
    I'm trying to send an e-mail using Google App Engine. I'm getting the exception below and I'm not sure why at the moment.

  • PHP sandbox/sanitize code passed to create_function

    - by kpowerinfinity
    Hello, I am using create_function to run some user-code at server end. I am looking for any of these two: Is there a way to sanitize the code passed to it to prevent something harmful from executing? Alternately, is there a way to specify this code to be run in a sandboxed environment so that the user can't play around with anything else. Thanks!

  • Enumerate registered namespaces of a PHP DOMDocument object

    - by zneak
    Hello world, For one of my projects, I'm using the DOMDocument class to load and manipulate XML documents. I'd need to retrieve every namespace used in the document; however, I can't find how I'd do that. The DOMDocument class has methods to get the namespace prefix of an URI or the URI of a namespace prefix, but I've seen nothing to actually enumerate registered namespaces. The SimpleXML library has a getNamespaces() method for that. Is there an equivalent for DOMDocument?

  • PHP SimpleXML - Remove xpath node

    - by Peter John
    Hi, I'm a little confused as to how i can delete a parent node of something which i can find via an xpath search: $xml = simplexml_load_file($filename); $data = $xml->xpath('//items/info[item_id="' . $item_id . '"]'); $parent = $data[0]->xpath("parent::*"); unset($parent); So, it finds the item id, no problems there - but the unset isnt getting rid of this <items> node. All i want to do is remove the <items>...</items> for this product. Obviously, there are loads of <items> nodes in the xml file so it cant do unset($xml->data->items) as that would delete everything. Any ideas much appreciated :-)

  • My PNG has transparency, but after saving with PHP GD, transparency is lost [closed]

    - by Harry Stroker
    I found the solution to my problem. See below the original post and completely at the bottom my solution. I made a stupid mistake :) First I crop an image and then save it to a png file. Right after this, I also show the image. However, the saved png does not have transparency and the shown one has. What is going on? $this->resource = imagecreatefrompng($this->url); imagealphablending($this->resource, false); imagesavealpha($this->resource, true); $newResource = imagecreatetruecolor($destWidth, $destHeight); imagealphablending($newResource, false); imagesavealpha($newResource, true); $resample = imagecopyresampled($newResource,$this->resource,0,0,$srcX1,$srcY1,$destWidth,$destHeight,$srcX2-$srcX1, $srcY2-$srcY1); imagedestroy($this->resource); $this->resource = $newResource; // SAVING imagepng($this->resource, $destination, 100); // SHOWING header('Content-type: image/png'); imagepng($this->resource); The reason I also save the image is for caching. If the script is executed on a png, it saves a cached png. Next time the image is requested, the png file will be shown, but it has lost its transparency. Even stranger: When I save that cached png image as (within Firefox), it saves it suddenly as a jpg, even though the extension was png. Downloading the cached png using chrome and opening it in Photoshop gives the error: "file-format module cannot parse the file". I will show you the shown PNG and the generated PNG: http://www.foodmuseum.nl/SaveProblemTransparency.png Once I try to show that saved PNG with the GD library, it gives me an error. EDIT NO NO NO NO THIS IS NOT A DUPLICATE!!!... I ALREADY USED THEIR SOLUTION. The solution in the supposedly duplicate works for showing my image. But I also try to save it with the exact same resource, but then it has no transparency. EDIT 2 - SOLUTION I found out what the problem was. It was a stupid mistake. The script I provided above were cut out of a class and placed as sequential code, while in real this is not what exactly happened. The save image function: function saveImage($destination,$quality = 90) { $this->loadResource(); switch($extension){ default: case 'JPG': case 'jpg': imagejpeg($this->resource, $destination, $quality); break; case 'gif': imagegif($this->resource, $destination); break; case 'png': imagepng($this->resource, $destination); break; case 'gd2': imagegd2($this->resource, $destination); break; } } However... $extension does not exist. I fixed it by adding: $extension = $this->getExtension($destination);

  • Get coordinates of google maps markers

    - by App_beginner
    I am creating a databse containing the names and coordinates of all bus stops in my local area. I have all the names stored in my database, and now I need to add the coordinates. I am trying to get these of a website that contains them all as placemarks on a google map. It seems to me like they are being generated from a local server, and then added to the map. However I am unable to find exactly where the server is queried for the coordinates. I am hoping to collect these coordinates through the use of a screen scraper. However unless I am able to find where in the source code the coordinates are created this seems to be impossible. I can of course search and collect all these placemarks manually, but that will be very time consuming. So I am hoping that someone in here can help me. This is the website I am trying to scrape. The placemarks are marked by the blue bus sign: http://reiseplanlegger.skyss.no/scripts/travelmagic/TravelMagicWE.dll/?from=Brimnes+ferjekai+%28Eidfjord%29&to= You can also get the coordinates of a single placemark by writing the name of the stop in the search field and pushing the "Vis i kart" button. I hope someone can help me with this.

  • 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
