    copied!<p>Two things:</p> <ol> <li>Using Javascript</li> <li>Using APC</li> </ol> <p><strong>Javascript:</strong></p> <pre><code>You can use plupload (http://www.plupload.com/) - pretty good multiple file uploader Pretty decent JS plugin for uploading files in PHP in two methods, 1. normal upload 2. chunk based uploading. </code></pre> <p>Limitations/Assumptions:</p> <pre><code>1. Flash Plugin - in the browser 2. Session problem - since it's flash, a different session's are created for each file upload. </code></pre> <p><strong>APC/PHP</strong></p> <p>Using APC - you can create a progress-bar on our own.</p> <p>Limitation/Assumptions:</p> <pre><code>1. Install APC on the server - using PECL (pecl install APC) 2. Write a separate code to get the status of upload. </code></pre> <p>Code:</p> <p><em>getprogress.php</em></p> <pre><code>&lt;?php if(isset($_GET['progress_key'])) { $status = apc_fetch('upload_'.$_GET['progress_key']); echo $status['current']/$status['total']*100; } ?&gt; </code></pre> <p><em>upload.php</em></p> <pre><code>&lt;?php $id = uniqid(""); ?&gt; &lt;html&gt; &lt;head&gt;&lt;title&gt;Upload Example&lt;/title&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;script type="text/javascript"&gt; function getProgress(){ $.get("getprogress.php?progress_key=&lt;?php echo($id)?&gt;", function(percent) { document.getElementById("progressinner").style.width = percent+"%"; if (percent &lt; 100){ setTimeout("getProgress()", 100); } }); } function startProgress(){ document.getElementById("progressouter").style.display="block"; setTimeout("getProgress()", 1000); } &lt;/script&gt; &lt;iframe id="theframe" name="theframe" src="fileupload.php?id=&lt;?php echo($id) ?&gt;" style="border: none; height: 100px; width: 400px;" &gt; &lt;/iframe&gt; &lt;br/&gt;&lt;br/&gt; &lt;div id="progressouter" style="width: 500px; height: 20px; border: 6px solid red; display:none;"&gt; &lt;div id="progressinner" style="position: relative; height: 20px; background-color: purple; width: 0%; "&gt; &lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><em>fileupload.php</em> </p> <pre><code>&lt;?php $id = $_GET['id']; ?&gt; &lt;form enctype="multipart/form-data" id="upload_form" action="target.php" method="POST"&gt; &lt;input type="hidden" name="APC_UPLOAD_PROGRESS" id="progress_key" value="&lt;?php echo $id?&gt;"/&gt; &lt;input type="file" id="test_file" name="test_file"/&gt;&lt;br/&gt; &lt;input onclick="window.parent.startProgress(); return true;" type="submit" value="Upload!"/&gt; &lt;/form&gt; </code></pre>
