You can easily check mime type of an internet resource using this code :

<?php
function getUrlMimeType($url) {
   
$buffer = file_get_contents($url);
   
$finfo = new finfo(FILEINFO_MIME_TYPE);
    return
$finfo->buffer($buffer);
}
?>

I'm using it to detect if an url given by a user is a HTML page (so I do some stuff with the HTML) or a file on Internet (so I show an icon accordingly to the mime type).

Get only a webpage content type and forget the charset

<?php
$file
= new finfo(FILEINFO_MIME);
echo
strstr($file->buffer(file_get_contents('http://example.com')),';',true)//Returns something similar to  text/html
?>
