Best method of uploading large files on server - php

Question

I made an ajax based multiple file upload which is working well enough. But the issue is I have to upload very large files means upto 200 MB of file each and may be 20-25 files of same size at the same time. Files are being uploaded but it takes very long time to upload.
I have changed several things in php ini settings
post_max_size 10G
upload_max_size 10G
max_execution_time 3600
memory_limit -1
So what is the best solution for handling such type of file upload, which perform fast.
My internet connection is of 100 MB/S and upload speed with 20 MB/S.
Please suggest me some good solution.

Depending on wich type of file you're uploading, you can try to send a zipped file to the server and unzip it when the upload is finished.
You can see more about zip functions in php here.
To zip one file:
Source: http://davidwalsh.name/create-zip-php
/* creates a compressed zip file */
function create_zip($files = array(),$destination = '',$overwrite = false) {
//if the zip file already exists and overwrite is false, return false
if(file_exists($destination) && !$overwrite) { return false; }
//vars
$valid_files = array();
//if files were passed in...
if(is_array($files)) {
//cycle through each file
foreach($files as $file) {
//make sure the file exists
if(file_exists($file)) {
$valid_files[] = $file;
}
}
}
//if we have good files...
if(count($valid_files)) {
//create the archive
$zip = new ZipArchive();
if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
return false;
}
//add the files
foreach($valid_files as $file) {
$zip->addFile($file,$file);
}
//debug
//echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status;
//close the zip -- done!
$zip->close();
//check to make sure the file exists
return file_exists($destination);
}
else
{
return false;
}
}
To unzip files in the server:
<?php
$zip = new ZipArchive;
$res = $zip->open('file.zip');
if ($res === TRUE) {
$zip->extractTo('/myzips/extract_path/');
$zip->close();
echo 'woot!';
} else {
echo 'doh!';
}
?>

From your application's point of view the only thing you can do is to limit the simultaneous file uploads. Extend your ajax multiple file upload script to upload just one file at a time. This probably will speed up things a little bit.
However your problem is probably not caused by the application itself, but by your server's network speed, or its disk writing speed. Some VPS providers also limits the number of disk write operations/sec. So, the best thing might be to migrate your app to another server with better network speed and performance. :)

The best way is to use old good FTP and some FTP clients like FileZilla for instance.
