jQuery and PHP examples

I use this function to determine duration of a FLV file. It works pretty cool. function mbmGetFLVDuration($file){ // read file if (file_exists($file)){ $handle = fopen($file, “r”); $contents = fread($handle, filesize($file)); fclose($handle); if (strlen($contents) > 3){ if (substr($contents,0,3) == “FLV”){ $taglen = hexdec(bin2hex(substr($contents,strlen($contents)-3))); if (strlen($contents) > $taglen){ $duration = hexdec(bin2hex(substr($contents,strlen($contents)-$taglen,3))); return $duration; } } } } [...]
