I am using the following code to download a file in PHP. Code works fine for most videos, but when I try to download video larger than 1 GB it failed and shows me a download error when it get to 1gb (exactly 1gb, no less, no more), this error happens with all browsers. But, if I use jdownloader or DownThemAll or any software all downloads are succesfully downloaded.

Code: Select all
<?php
set_time_limit(0);
ini_set('memory_limit', '2G');

function getMimeType($fileName)
{
    $c_type_default = "application/octet-stream";
    $content_types = array(
        "exe" => "application/octet-stream",
        "zip" => "application/zip",
        "mp3" => "audio/mpeg",
        "mpg" => "video/mpeg",
        "avi" => "video/x-msvideo",
         "mp4" => "video/mp4",
    );
//  echo isset($content_types[pathinfo($fileName, PATHINFO_EXTENSION)]) ? $content_types[pathinfo($fileName, PATHINFO_EXTENSION)] : $c_type_default;     
    return isset($content_types[pathinfo($fileName, PATHINFO_EXTENSION)]) ? $content_types[pathinfo($fileName, PATHINFO_EXTENSION)] : $c_type_default;
}
function output_file($file, $name)

Are you sure that wherever you're running this the ini_set commands actually do something? On shared hosting you probably won't be able to do anything about memory limits and timeouts.
