Large Resource

Here is the simple script to copy large file from one server to another server without downloading it to local machine.

<?php
    $in = fopen("http://xyz.com/backup.tar.gz", "rb");
    $out = fopen("backup.tar.gz", "w+");
    echo pipe_streams($in, $out);

    function pipe_streams($in, $out)
    {
        $size = 0;
        while (!feof($in)) $size += fwrite($out,fread($in,8192));
        return $size;
    }
?>

Create a download.php in your destination server and change the filename to be downloaded and created.
It will avoid user’s bandwidth and time and it is the easiest way to copy the large backup files from one server to another server, while changing the hosting server.
