is possible , how determine if given string of filename or url valid resource video? have project fetches data rss feed , filter videos. idea? in advance.

what need curl_getinfo():

<?php // file headers $ch = curl_init('http://www.test.com/data.avi'); curl_setopt($ch, curlopt_returntransfer, true); curl_exec($ch);  // content type $allowed_content_types = array("video/x-msvideo", "video/mp4"); $content_type = curl_getinfo($ch, curlinfo_content_type); if (in_array($content_type, $allowed_content_types) {     // code here }

if want check file extensions - can explode url string dot, latest element , use in_array check if in array of allowed extensions:

  $url = "http://test.com/data.avi"; $extension = pathinfo("test.s.d", pathinfo_extension); $allowed_extensions = array("avi", "mp4"); if (in_array($extension, $allowed_extensions) {     // code here }
