Getting MIME of remote file with Zend Framework

Friday, 09 April 2010
If you ever need to get content type of remote file from within PHP, this class will come in handy. Supposing you need to check external link if it is an mp3 file. You will be able to do this: $sniffer = new Smartycode_Http_Mime();
$contentType = $sniffer->getMime($url);
if('audio/mpeg3' == $contentType) echo 'It is MP3';
<?php
/*
* @author Danila Vershinin (smartycode.com)
*/

require_once 'Zend/Http/Client.php';
class Smartycode_Http_Mime {

private static $client = null;

public function getMime($url) {
if (!self::$client) {
self::$client = new Zend_Http_Client();
self::$client->setConfig(array(
'maxredirects' => 5,
'timeout' => 30,
'strictredirects' => true));
}

try {
self::$client->setUri($url);
} catch (Exception $e) {
Zend_Registry::get('logger')->debug($url. ' is not valid URL by W3C rules');
return null;
}
//$client = new Zend_Http_Client($url);
$mime = null;
try {
$response = self::$client->request('HEAD');
$content_type = $response->getHeader('Content-Type');
if (is_array($content_type) && count($content_type)) $content_type = $content_type[0];
list($mime) = explode(';', $content_type);

} catch (Exception $e) {
Zend_Registry::get('logger')->debug('Error while getting mime type for '.$url);
unset($response);
unset($content_type);
}
unset($client);
return $mime;
}

}

?>
