PHP upload with APC in lightppd

I'm using APC to make a upload meter. These are the files:

• Form
• Upload Meter
• php.ini
开发者_高级运维

The problem I'm having is I'm getting nothing when I do the FETCH. I'm taking a look at the APC INFO panel as I'm making the upload and I see that the key upload_XXXXX isn't stored in the cache until the file is completely uploaded!

What am I doing wrong? Do I have something badly configured in php.ini?

I've read here that there's a bug having to do with lightppd.

As discussed in the comments, APC's file upload progress indicator is either unreliable or not functional under FastCGI.

Your best bet for a upload progress indicator is therefore going to be client-side.

I'm a big fan of Plupload, an upload widget that supports no less than six backends to provide better functionality than the regular file input type (including the HTML5 File interface in browsers that support it). You can use it standalone with a custom widget of your own design, or you can use the included fancy jQuery widget.

If you want something a little more oldschool, there's also good old SWFUpload.

Both of these options will fall back to a normal file input when Javascript is disabled.

Sorry, this isn't a direct answer to your question, but you may want to consider the HTML5 file API with XMLHttpRequest.

var req = new XMLHttpRequest();
req.upload.addEventListener("progress", updateProgress, false);
// ...
req.open();
// ...

There are some examples on developer.mozilla.org.

The downside is that it is browser dependent. The upside is that it is server independent. But ultimately, this will be the best way to track file uploads.
