php上传大文件

Question

I'm stuck here with file uploading problem. I've searched for answers but found only "increasing post_max_size and upload_max_filesize" suggestion and that doesn't work for me. I can't get large files uploaded(approx. around 150mb+), the following are my php.ini settings and my environments

php.ini

 - max_input_time 300
 - max_execution_time 600
 - memory_limit 1024M
 - upload_max_filesize 1512M
 - post_max_size 2048M

environments

 - Webserver: XAMPP
 - PHPFramwork: CodeIgniter

I've also tried many other php.ini configurations. The file uploading class that I've built received posted file data from XmlHttpResponse request using xhr.send(file). I've debugged infos with firebug header is normal, post totally empty (normally it should be the file data, an in-read-able text), cookies are the ci_session cookies, and no xhr response text at all. I've write a script that will return some response no matter what, though.

I'm no experts in this, rather a newbie. This all information at hand that I can give to you guys. So, any ideas on what happen in this? I'm really stuck here can't get this problem solve.

If there should be any info that I can look for and give it to you to get this problem solved do tell me so.

thx in advance.

Answer 1

instead uploading with standard form try uploading with xhr object (as you said) but using file chunk method to send file to server, in this way theorically you should have not upload limits. Try this upload jquery plugin that provides also php scripts:

Answer 2

If you are uploading very large files such as a few GB, then there are actually browser side limitations. It appears that most modern browsers are 2GB - 4GB . You should probably look into chunking (uploading parts of the file like a few MB at a time) your file uploads.
