Once I asked this same question but now I can give a test case for it.
The problem resides in debugging in Eclipse PDT when the page sends multiple requests to the server's dynamic pages. Consider a web page as follow:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script src="link-to-jquery/jquery-1.7.2.min.js"></script>
<script>
$(document).ready(function() {
var list = $("ol");
for (var i=0; i<20; i++) {
list.append($('<li><img src="/img.php?'+i+'" /></li>'));
}
});
</script>
</head>
<body>
<ol>
</ol>
</body>
</html>
In above page, JQuery is used only to prevent browser from caching the images. And the the img.php reads like this:
<?php
readfile('some_image.jpg');
When I try to debug the first page in the Eclipse PDT, using Zend Debugger, only the first img.php request is made and others are dismissed. A sample output is shown in the attached image file. In the presented case, not loading an image file won't prevent you from debugging the rest of project. But once there's a javascript file which isn't loaded because of this problem, the rest of project won't work as it has to. Does anyone know how can I debug such a page?
Here are my specifications:
- PHP Version 5.3.14
- Zend Debugger v5.3
- Eclipse for PHP Developers, Version: 3.0.2
- Apache/2.2.22 (Ubuntu)
I found that this problem is specific to Zend Debugger and XDebug works smoothly.
+1 for XDebug, -1 for Zend Debugger
