This is by far (after hours of googling and trying scripts) the simplest to set up and nicest uploader I've found

<a href="https://github.com/FineUploader/fine-uploader" rel="noreferrer">https://github.com/FineUploader/fine-uploader</a>

It doesn't require APC or any other external PHP libraries, I can get file progress feedback on a shared host, and it claims to support html5 drag and drop (personally untested) and multiple file uploads.

blocks|key|1561294|text|如果你安装了APC，它有一个上载进度的回调钩子。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1561295|Rasmus+Lerdorf+(PHP的创建者)有一个使用YUI的sample+(哦，这是PHP+source)。|1561296|参见the+documentation+here。|1561297|entityMap|0|LINK|mutability|MUTABLE|url|http://php.net/apc|1|http://progphp.com/progress.php|2|http://progphp.com/progress.phps|3|http://php.net/manual/en/apc.configuration.php#ini.apc.rfc1867^0|6|3|0|0|X|6|1|19|A|2|0|2|M|3|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]]|C|$]]|$1|D|3|E|5|6|7|Z|8|@]|9|@$A|10|B|11|1|12]|$A|13|B|14|1|15]]|C|$]]|$1|F|3|G|5|6|7|16|8|@]|9|@$A|17|B|18|1|19]]|C|$]]|$1|H|3|-4|5|6|7|1A|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]|R|$5|K|L|M|C|$N|S]]|T|$5|K|L|M|C|$N|U]]]]

If you have <a href="http://php.net/apc" rel="nofollow noreferrer">APC</a> installed, it has a callback hook for upload progress.

Rasmus Lerdorf (PHP's creator) has a <a href="http://progphp.com/progress.php" rel="nofollow noreferrer">sample</a> of this using YUI (oh, and here's the <a href="http://progphp.com/progress.phps" rel="nofollow noreferrer">PHP source</a>).

blocks|key|1345465|text|我很抱歉地说，就我所知，由于PHP的工作方式，纯PHP上传进度条，甚至PHP/Javascript上传进度条都不可能实现。你最好的选择就是使用某种形式的Flash+uploader。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1345466|AFAIK这是因为您的脚本在填充所有超全局变量之前不会执行，其中包括$_FILES。在调用PHP脚本时，文件已完全上载。|1345467|编辑:这不再是真的。那是在2010年。|1345468|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I'm sorry to say that to the best of my knowledge a pure PHP upload progress bar, or even a PHP/Javascript upload progress bar is not possible because of how PHP works. Your best bet is to use some form of Flash uploader.

AFAIK This is because your script is not executed until all the superglobals are populated, which includes $_FILES. By the time your PHP script gets called, the file is fully uploaded.

EDIT: This is no longer true. It was in 2010.

One PHP-ish (5.2+) &amp; no-Flash way that worked nicely for me:

First, see <a href="http://www.php.net/manual/en/features.file-upload.php#71564" rel="nofollow noreferrer">this</a> post explaining how to get "uploadprogress" extension up and running.

Then, in the page containing the form that you are uploading file(s) from, create the following iframe:

<pre><code>&lt;iframe id="progress_iframe" src="" style="display:none;" scrolling="no" frameborder="0"&gt;&lt;/iframe&gt;
</code></pre>

Next, add this code to your "Submit" button:

<pre><code>onclick="function set() { f=document.getElementById('progress_iframe'); f.style.display='block'; f.src='uploadprogress.php?id=&lt;?=$upload_id?&gt;';} setTimeout(set);"
</code></pre>

Now you have a hidden iframe in your form that will come visible and show contents of uploadprogress.php when you click "Submit" to start uploading files. $upload_id must be the same that you are using as the value of hidden field "UPLOAD_IDENTIFIER" in your form.

The uploadprogress.php itself looks about like this (fix and adjust to your needs):

<pre><code>&lt;html&gt;
&lt;head&gt;
&lt;META HTTP-EQUIV='REFRESH' CONTENT='1;URL=?id=&lt;?=$_GET['id']?&gt;'&gt;
&lt;/head&gt;
&lt;body&gt;
Upload progress:&lt;br /&gt;
&lt;?php
 if(!$_GET['id']) die;
 $info = uploadprogress_get_info($_GET['id']);
 $kbytes_total = round($info['bytes_total'] / 1024);
 $kbytes_uploaded = round($info['bytes_uploaded'] / 1024);
 echo $kbytes_uploaded.'/'.$kbytes_total.' KB';
?&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

Note that is self-refreshes every second. You can surely add some nice visual progress bar here (like 2 nested &lt;div&gt;s with different colors) if you like. The iframe with upload progress naturally only works while the upload is in progress, and ends its visible life once the form is submitted and browser reloads to the next page.

blocks|key|1345899|text|HTML5引入了一个file+upload+api，它允许你监控文件上传的进度，但对于较老的浏览器，有一个plupload，一个专门用来监控文件上传并提供相关信息的框架。另外，它有大量的回调函数，所以它可以在所有浏览器上运行|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1345900|entityMap|0|LINK|mutability|MUTABLE|url|http://www.matlus.com/html5-file-upload-with-progress/|1|http://www.plupload.com/index.php^0|A|F|0|1H|8|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

blocks|key|1345544|text|您需要使用Javascript来创建进度条。通过简单的谷歌搜索，我找到了这篇文章：WebAppers+Simple+Javascript+Progress+Bar+with+CSS。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1345545|Dojo+File+Upload+Progress+Bar+Widget是使用Dojo+Javascript框架的另一个选择。|1345546|编辑:假设您上传了大量图像(例如相册)，并将它们编辑到您的PHP脚本中，您可以使用javascript从帖子中读取结果，并根据上传的图像数量/图像总数来更新进度条。这有一个副作用，那就是只有在每个帖子完成后才会更新。有关如何在JS上发帖的信息，请查看here。|1345547|entityMap|0|LINK|mutability|MUTABLE|url|http://www.webappers.com/2007/07/31/webappers-simple-ajax-progress-bar-with-css/|1|http://ajaxian.com/archives/dojo-file-upload-progress-bar-widget|2|http://mentaljetsam.wordpress.com/2008/06/02/using-javascript-to-post-data-between-pages/^0|15|1D|0|0|0|10|1|0|3H|4|2|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|D|3|E|5|6|7|X|8|@]|9|@$A|Y|B|Z|1|10]]|C|$]]|$1|F|3|G|5|6|7|11|8|@]|9|@$A|12|B|13|1|14]]|C|$]]|$1|H|3|-4|5|6|7|15|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]|R|$5|K|L|M|C|$N|S]]]]

You would need to use Javascript to create a progress bar. A simple Google search led me to this article: <a href="http://www.webappers.com/2007/07/31/webappers-simple-ajax-progress-bar-with-css/" rel="nofollow noreferrer">WebAppers Simple Javascript Progress Bar with CSS</a>.

<a href="http://ajaxian.com/archives/dojo-file-upload-progress-bar-widget" rel="nofollow noreferrer">Dojo File Upload Progress Bar Widget</a> is another option using the Dojo Javascript framework.

EDIT: Assuming your uploading a large number of images (such as a photo album), and POSTing them to your PHP script, you could use javascript to read the results back from the post and update the progress bar based on the number of images uploaded / total number of images. This has the side effect of only updating after each post has completed. Check out <a href="http://mentaljetsam.wordpress.com/2008/06/02/using-javascript-to-post-data-between-pages/" rel="nofollow noreferrer">here</a> for some info on how to post with JS.

blocks|key|1561214|text|可以创建一个php/ajax进度条。(查看pear中的Html_Ajax库)。但是，这需要在php中安装一个自定义模块。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1561215|其他方法需要使用iframe，php通过它来查看上传了多少文件。然而，这种隐藏的iframe可能会被一些浏览器插件阻止，因为隐藏的iframe经常被用来向用户的计算机发送恶意数据。|1561216|如果您无法控制您的服务器，最好的办法是使用某种形式的flash进度条。|1561217|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

A php/ajax progress bar can be done. (Checkout the Html_Ajax library in pear).
However this requires installing a custom module into php.

Other methods require using an iframe, through which php looks to see how much of the file has been uploaded. However this hidden iframe, may be blocked by some browsers addons because hidden iframes are often used to send malicious data to a users computer.

Your best bet is to use some form of flash progress bar if you do not have control over your server.

Does anyone know how to get a progress bar for an upload in php? I am trying writing code for a photo album uploader. I would like a progress bar to display while the photos are uploading. 

I am fairly new to php so I dont know everything about it.
