  • file_get_contents() removing tab and new line characters

    - by Patrick Murray
    I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

  • strange behavior while including a class in php

    - by user1864539
    I'm experiencing a strange behavior with PHP. Basically I want to require a class within a PHP script. I know it is straight forward and I did it before but when I do so, it change the behavior of my jquery (1.8.3) ajax response. I'm running a wamp setup and my PHP version is 5.4.6. Here is a sample as for my index.html head (omitting the jquery js include) <script> $(document).ready(function(){ $('#submit').click(function(){ var action = $('#form').attr('action'); var form_data = { fname: $('#fname').val(), lname: $('#lname').val(), phone: $('#phone').val(), email: $('#email').val(), is_ajax: 1 }; $.ajax({ type: $('#form').attr('method'), url: action, data: form_data, success: function(response){ switch(response){ case 'ok': var msg = 'data saved'; break; case 'ko': var msg = 'Oops something wrong happen'; break; default: var msg = 'misc:<br/>'+response; break; } $('#message').html(msg); } }); return false; }); }); </script> body <div id="message"></div> <form id="form" action="handler.php" method="post"> <p> <input type="text" name="fname" id="fname" placeholder="fname"> <input type="text" name="lname" id="lname" placeholder="lname"> </p> <p> <input type="text" name="phone" id="phone" placeholder="phone"> <input type="text" name="email" id="email" placeholder="email"> </p> <input type="submit" name="submit" value="submit" id="submit"> </form> And as for the handler.php file: <?php require('class/Container.php'); $filename = 'xml/memory.xml'; $is_ajax = $_REQUEST['is_ajax']; if(isset($is_ajax) && $is_ajax){ $fname = $_REQUEST['fname']; $lname = $_REQUEST['lname']; $phone = $_REQUEST['phone']; $email = $_REQUEST['email']; $obj = new Container; $obj->insertData('fname',$fname); $obj->insertData('lname',$lname); $obj->insertData('phone',$phone); $obj->insertData('email',$email); $tmp = $obj->give(); $result = $tmp['_obj']; /* Push data inside array */ $array = array(); foreach($result as $key => $value){ array_push($array,$key,$value); } $xml = simplexml_load_file($filename); // check if there is any data in if(count($xml->elements->data) == 0){ // if not, create the structure $xml->elements->addChild('data',''); } // proceed now that we do have the structure if(count($xml->elements->data) == 1){ foreach($result as $key => $value){ $xml->elements->data->addChild($key,$value); } $xml->saveXML($filename); echo 'ok'; }else{ echo 'ko'; } } ? The Container class: <?php class Container{ private $_obj; public function __construct(){ $this->_obj = array(); } public function addData($data = array()){ if(!empty($data)){ $oldData = $this->_obj; $data = array_merge($oldData,$data); $this->_obj = $data; } } public function removeData($key){ if(!empty($key)){ $oldData = $this->_obj; unset($oldData[$key]); $this->_obj = $oldData; } } public function outputData(){ return $this->_obj; } public function give(){ return get_object_vars($this); } public function insertData($key,$value){ $this->_obj[$key] = $value; } } ? The strange thing is that my result always fall under the default switch statement and the ajax response fit both present statement. I noticed then if I just paste the Container class on the top of the handler.php file, everything works properly but it kind of defeat what I try to achieve. I tried different way to include the Container class but it seem to be than the issue is specific to this current scenario. I'm still learning PHP and my guess is that I'm missing something really basic. I also search on stackoverflow regarding the issue I'm experiencing as well as PHP.net, without success. Regards,

  • How to access controls collection of dynamically loaded aspx page?

    - by Naasir
    Let's say I have two webforms, A.aspx and B.aspx, where B.aspx contains some simple web controls such as a textbox and a button. I'm trying to do the following: When A.aspx is requested, I want to dynamically call and load B.aspx into memory and output details of all the controls contained in B.aspx. Here is what I tried in the codebehind for A.aspx: var compiledType = BuildManager.GetCompiledType("~/b.aspx"); if (compiledType != null) { var pageB = (Page)Activator.CreateInstance(compiledType); } foreach (var control in pageB.Controls) { //output some details for each control, like it's name and type... } When I try the code above, the controls collection for pageB is always empty. Any ideas on how I can get this to work? Some other important details: both webforms utilize a master page (so the web controls in b.aspx are actually placed within a "content" tag) I've also tried using BuildManager.CreateInstanceFromVirtualPath. No luck.

  • Replace strings differently depending if is enclosed in braces or not.

    - by peroyomas
    I want to replace all instances of an specific words between braces with something else, unless it is written between double braces, while it should show as is it was written with single braces without the filter. I have tried a code but only works for the first match. The rest are shown depending of the first one: $foo = 'a {bar} b {{bar}} c {bar} d'; $baz = 'Chile'; preg_match_all( '/(\{?)\{(tin)\}(\}?)/i', $foo, $matches, PREG_SET_ORDER ); if ( !empty($matches) ) { foreach ( (array) $matches as $match ) { if( empty($match[1]) && empty($match[3])) { $tull = str_replace( $match[0], $baz, $foo ); } else { $tull = str_replace( $match[0], substr($match[0], 1, -1), $foo ) ; } } } echo $tull;

  • How to import datarow from one dataset to another?

    - by Disciple
    Hi, I want to copy the row to the new dataset if the previous value in second column isn't the same as the current one (i.e this dataset should have rows with unique values): DataTable tbl = new DataTable(); DataTable tmpTable = ds.Tables[0]; for( var rowIndex = 0; rowIndex < ds.Tables[0].Rows.Count; rowIndex++ ) { object value = null; foreach (DataRow x in tbl.Rows) { if (ds.Tables[0].Rows[rowIndex][1] == x[1]) { value = ds.Tables[0].Rows[rowIndex][1]; break; } } // value already exists if (value == null) { tbl.ImportRow(ds.Tables[0].Rows[rowIndex]); } } How to do this correctly? Maybe one loop instead 2?

  • Allow alphanumeric, punctuation, and spaces

    - by bccarlso
    I'm pretty new to regular expressions, and MAN do they give me a headache. They are so intimidating! For an email campaign I'm doing, a user will click a link out of the email with a few URL parameters filled in for them, to make filling out a form easier. I want to prevent any injection hacks or whatever it's called, but need to allow the $_GET parameters to be alphanumeric, have punctuation, and have spaces. If someone has a good method for this, I'd appreciate it, but right now I have: foreach($_GET as $m=>$n) { $get[$m] = preg_replace('(^[a-z0-9 \-\_\.]+)i',' ',$n); } I would like to be able to replace all characters NOT found with this regular expression, which I believe I use ?!, but I can't get that to work either. Any help in getting this to work would be appreciated!

  • Threading and iterating through changing collections

    - by adamjellyit
    In C# (console app) I want to hold a collection of objects. All objects are of same type. I want to iterate through the collection calling a method on each object. And then repeat the process continuously. However during iteration objects can be added or removed from the list. (The objects themselves will not be destroyed .. just removed from the list). Not sure what would happen with a foreach loop .. or other similar method. This has to have been done 1000 times before .. can you recommend a solid approach?

  • Forcing a mixed ISO-8859-1 and UTF-8 multi-line string into UTF-8 in Perl

    - by knorv
    Consider the following problem: A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1. I don't know a priori which lines are in which encoding, so heuristics will be needed. I want to turn $junk into pure UTF-8 with proper re-encoding of the ISO-8859-1 lines. Also, in the event of errors in the processing I want to provide a "best effort result" rather than throwing an error. My current attempt looks like this: $junk = &force_utf8($junk); sub force_utf8 { my $input = shift; my $output = ''; foreach my $line (split(/\n/, $input)) { if (utf8::valid($line)) { utf8::decode($line); } $output .= "$line\n"; } return $output; } While this appears to work I'm certain this is not the optimal solution. How would you improve the force_utf8(...) sub?

  • Do I have to hash twice in C#?

    - by Joe H
    I have code like the following: class MyClass { string Name; int NewInfo; } List<MyClass> newInfo = .... // initialize list with some values Dictionary<string, int> myDict = .... // initialize dictionary with some values foreach(var item in newInfo) { if(myDict.ContainsKey(item.Name)) // 'A' I hash the first time here myDict[item.Name] += item.NewInfo // 'B' I hash the second (and third?) time here else myDict.Add(item.Name, item.NewInfo); } Is there any way to avoid doing two lookups in the Dictionary -- the first time to see if contains an entry, and the second time to update the value? There may even be two hash lookups on line 'B' -- one to get the int value and another to update it.

  • How to seperate database entries and display them as individual records using PHP?

    - by Clark
    I used to have database entries separated by ampersands (&), but this was causing certain search issues so I decided to encapsulate my entries on both sides by $ and & symbols like: $this& But I am having trouble displaying all the entries of a cell as indiivdual records. Before I used: $unsplitItems = $row['files']; $files = explode("@", $unsplitItems); foreach ($files as $file) { if(strlen($file)) { echo "<li>$file</li>"; } } Any idea how I can split my records and display all the items in the array as individual entries?

  • How can I display more info in an error message when using NUnit Assert in a loop?

    - by Ian
    Consider the following code: [Test] public void WidgetTest() { foreach (Widget widget in widgets) { Assert.AreEqual(0, widget.SomeValue); } } If one of the asserts fails, I will get a very unhelpful error message like the one below: 1) Test Failure : WidgetTest.TestSomeValue Expected: 0 But was: 1 at WidgetTest.TestSomeValue() So, the question is, how can I get NUnit to display more useful info, such as the name of the widget, or the iteration of the loop, etc? Even a line number would be more helpful, since this is run in automated manner and I'd like to be able to spot the failing assert without debugging into the code.

  • Intersection between sets containing different types of variables

    - by Gacek
    Let's assume we have two collections: List<double> values List<SomePoint> points where SomePoint is a type containing three coordinates of the point: SomePoint { double X; double Y; double Z; } Now, I would like to perform the intersection between these two collections to find out for which points in points the z coordinate is eqal to one of the elements of values I created something like that: HashSet<double> hash = new HashSet<double>(points.Select(p=>p.Z)); hash.IntersectWith(values); var result = new List<SomePoints>(); foreach(var h in hash) result.Add(points.Find(p => p.Z == h)); But it won't return these points for which there is the same Z value, but different X and Y. Is there any better way to do it?

  • asp.net web form Cutom Router Handler

    - by jparram
    I am using a custom route handler for a webforms application. I am using routes to determine localization. ie: if the url has es or fr in the route it will load either spanish or french resources. for example: www.someroute/es/checkstuff/checkstuff.aspx will load: www.someroute/checkstuff/checkstuff.aspx with the spanish resources. I am configuring the custom routes in global.asax via: protected void Application_Start(object sender, EventArgs e) { RegisterRoutes(RouteTable.Routes); } public static void RegisterRoutes(RouteCollection routes) { foreach (var value in _customRoutes) { routes.Add(value.RouteName, new Route(value.Route, new CustomRouteHandler(value.ResolvedRoute))); } } where _customroutes is a list of routes. Is there a way to do this with some kind of pattern matching so I can avoid adding a specific route for each page in the application. While I know I could use a t4 template to generate the routes, I guess I am looking for a dynamic way to create the list
