php - Get the real video URL from a url -


i'm trying real file url url doesn't show real file name.

my url http://video.premium.com/file/ee7bfec921cfbe16e6f08e282992b99670a00ca3/3

if real file url stream directly online through web player, needs .mp4 or other file format play, url http://video.premium.com/file/ee7bfec921cfbe16e6f08e282992b99670a00ca3/3 doesnt work.

but when open url using vlc media player, works. doesn't work online flash or other players..

is possible? anyway this?

with curl, use this: follows redirect until finds endpoint. in included code used goo.gl shorten url rando image. see output original link (and output whatever number of redirects , urls), , final redirect actual file. think looking for. did not write originally, found somewhere time ago , reused many times again tweaking when needed. seems fit in many places. glad pass on. think might achieve looking for. 

<?php function follow_redirect($url){    $redirect_url = null;      if(function_exists("curl_init")){       $ch = curl_init($url);       curl_setopt($ch, curlopt_header, true);       curl_setopt($ch, curlopt_nobody, true);       curl_setopt($ch, curlopt_returntransfer, true);       $response = curl_exec($ch);       curl_close($ch);    }    else{       $url_parts = parse_url($url);       $sock = fsockopen($url_parts['host'], (isset($url_parts['port']) ? (int)$url_parts['port'] : 80));       $request = "head " . $url_parts['path'] . (isset($url_parts['query']) ? '?'.$url_parts['query'] : '') . " http/1.1\r\n";       $request .= 'host: ' . $url_parts['host'] . "\r\n";       $request .= "connection: close\r\n\r\n";       fwrite($sock, $request);       $response = fread($sock, 2048);       fclose($sock);    }      $header = "location: ";    $pos = strpos($response, $header);    if($pos === false){       return false;    }    else{       $pos += strlen($header);       $redirect_url = substr($response, $pos, strpos($response, "\r\n", $pos)-$pos);       return $redirect_url;    } }  $url = 'http://goo.gl/66vjb';   echo '<ol>'; while(($newurl = follow_redirect($url)) !== false){    echo '<li>', $url, '</li>';    $url = $newurl; } echo '</ol>';   echo '<a href="', $url, '">', $url, '</a>'; ?>

output:

  1. http://goo.gl/66vjb
