I have a web application that accepts file uploads of up to 4 MB. The server side script is PHP and web server is NGINX. Many users have requested to increase this limit drastically to allow upload of video etc.
However there seems to be no easy solution for this problem with PHP. First, on the client side I am looking for something that would allow me to chunk files during transfer. SWFUpload does not seem to do that. I guess I can stream uploads using Java FX (http://blogs.oracle.com/rakeshmenonp/entry/javafx_upload_file) but I can not find any equivalent of request.getInputStream in PHP.
Increasing browser client_post limits or php.ini upload or max_execution times is not really a solution for really large files (~ 1GB) because maybe the browser will time out and think of all those blobs stored in memory.
Is there any way to solve this problem using PHP on server side? I would appreciate your replies.
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.
Try using the bigupload script. It is very easy to integrate and can upload up to 2 Gb in chunks. The chunk size is customizable.
Take a look at tus protocol which is a HTTP based protocol for resumable file uploads so you can carry on where you left off without re-uploading whole data again in case of any interruptions. This protocol has also been adopted by vimeo from May, 2017.
You can find various implementations of the protocol in different languages here. In your case, you can use its javascript client called uppy and use golang or php based server implementation in a server.
How about using a java applet for the uploading and PHP for processing..
You can find an example here for Jupload: http://sourceforge.net/apps/mediawiki/jupload/index.php?title=PHP_Example
you can use this package
it supports resumable chunk upload.
in the examples/js-examples/resumable-chunk-upload example , you can close and re-open the browser and then resume not completed uploads.
You can definitely write a web app that will accept a block of data (even via a POST) then append that block of data to a file. It seems to me that you need some kind of client side app that will take a file and break it up into chunks, then send it to your web service one chunk at a time. However, it seems a lot easier to create an sftp dir, and let clients just sftp up files using some pre-existing client app.
