This post i am explain about how to download file based on given speed limit. This test.zip file is downloaded based on the speed limit what we given in the code. IMAGES.zip is a target file and i fixed the 80 as a speed you can change this and then try this download speed.
Download file script with speed Limit:
<?php
$target_file = ‘IMAGES.zip’;
$download_speed = 80;
if(file_exists($target_file) && is_file($target_file)) {
header(‘Cache-control: private’);
header(‘Content-Type: application/octet-stream’);
header(‘Content-Length: ‘.filesize($target_file));
header(‘Content-Disposition: filename=’.$target_file);
flush();
$file = fopen($target_file, “r”);
while (!feof($file)) {
print fread($file, round($download_speed * 1024));
flush();
sleep(1);
}
fclose($file);
}
else {
die(‘Error: The file ‘.$target_file.’ does not exist!’);
}
?>
