Re: How to count transfered kBytes in File-Download

> echo fread($HANDLER, $FSIZE); This is your problem child right here... Sucking in an entire OGG File to RAM, for a large OGG file, will be quite painful. And, on a busy server, even moderate size files will be problematic. You could probably relieve a lot of stress and keep full-size downloads just by doing: define('CHUNK_SIZE', 2048); define('DOWNLOAD_LIMIT', 10*1024); while (!feof($HANDLER)){ echo fread($HANDLER, CHUNK_SIZE); } To answer your original question, you would abort this loop partway though, using some kind of counter *= CHUNK_SIZE and compare it to DOWNLOAD_LIMIT.
