Limit download speed using PHP

Question

I found on Google some PHP scripts to limit the download speed of a file, but the file download at 10 Mbps or if it download at 80 kbps as i set it, after 5 mb, it stops dow

Answer 1

First of all max_execution_time is the execution time of your script. Sleeping is not part of it.

Regarding speed limiting you could use something like a Token bucket. I've put everything into one convenient library for you: bandwidth-throttle/bandwidth-throttle

use bandwidthThrottle\BandwidthThrottle;

$in  = fopen(__DIR__ . "/resources/video.mpg", "r");
$out = fopen("php://output", "w");

$throttle = new BandwidthThrottle();
$throttle->setRate(100, BandwidthThrottle::KIBIBYTES); // Set limit to 100KiB/s
$throttle->throttle($out);

stream_copy_to_stream($in, $out);
