Upload 1GB files using chunking in PHP
plupload is a javascript/php library, and it's quite easy to use and allows chunking.
It uses HTML5 though.
"but I can not find any equivalent of request.getInputStream in PHP. "
fopen('php://input'); perhaps?
I have created a JavaFX client to send large files in chunks of max post size (I am using 2 MB) and a PHP receiver script to assemble the chunks into original file. I am releasing the code under apache license here : http://code.google.com/p/gigaupload/ Feel free to use/modify/distribute.
