If you want to download files from a linux server with a filesize bigger than 2GB you can use the following:



<?php

function serveFile( $file , $as ){

    header( 'Expires: Mon, 1 Apr 1974 05:00:00 GMT' );

    header( 'Pragma: no-cache' );

    header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' );

    header( 'Content-Description: File Download' );

    header( 'Content-Type: application/octet-stream' );

    header( 'Content-Length: '.trim(`stat -c%s "$file"`) );

    header( 'Content-Disposition: attachment; filename="'. $as .'"' );

    header( 'Content-Transfer-Encoding: binary' );

    //@readfile( $file );



    flush();

    $fp = popen("tail -c ".trim(`stat -c%s "$file"`)." ".$file.' 2>&1', "r");

    while(!feof($fp))

    {

        // send the current file part to the browser

        print fread($fp, 1024);

        // flush the content to the browser

        flush();

    }

    fclose($fp);

}

?>
