Checking media type of audio and video from external links in php

Question

Does any one know how to check media types of audio and video from external urls.

function get_url_mime_type($url) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_exec($ch);
    return curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
}

you mean the media's MIME type ? or its codec ? what have you tried ? — Raptor, Apr 23 '13 at 06:42

To get file's MIME, use the following codes:

<?php
$finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); // return mime type a.k.a. mimetype extension

/* get mime-type for a specific file */
$filename = "/usr/local/something.txt";
echo $finfo->file($filename);
?>

To get the extension of the file:

$tokens = explode('.', $filename);
$extension = $tokens[count($tokens)-1];

To get the MIME type of external file, either you can use cURL HEAD request to get the header ( may not be accurate , as web server may not response with correct answer ), or use getID3.

This question also asks the similar thing. Take a look of it.

Reference: finfo_open()

if i use curl_getinfo() some times for audio urls i got media type "text/html" that's the problem. – Apr 23 '13 at 07:29
Do you use HEAD request as my referenced question ? – Raptor Apr 23 '13 at 08:30
got it ! but you are not requesting a file. You are requesting a page. Your URL should look like http://www.example.com/example.mp3 – Raptor Apr 23 '13 at 09:01
