Fast function to check if url exists PHP

I used @file_get_contents and get_headers, both are slow even if the URL is below 1ko, tried to use cURL but it isn't supported by the server. Is there any fast fucntion to use instead ?

Frank Koehl did a neat little function to do just that and return the url’s http status.

http status code function

/**
 * @author  Frank Koehl
 * @src    http://frankkoehl.com/2009/09/http-status-code-curl-php/
 */
function get_status($url)
{
    // must set $url first. Duh...
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    // do your curl thing here
    $data = curl_exec($ch);
    $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    return $http_status;
}

using the method suggested by @arkascha you could do something like this:

$url='http://stackoverflow.com';
$options=array(
    'http'=>array(
        'method'        =>  'HEAD',
        'User-Agent'    =>  $_SERVER['HTTP_USER_AGENT']
    )
);
stream_context_get_default( $options );
$headers=get_headers( $url, 1 );
echo $headers[0];

It seems fairly quick and you could further parse the response to find if the status is 200 or otherwise.
