Read One URl Parameter using php

I want to read one parameter from a specific URl :

Like : http://www.youtube.com/watch?v=MrOiL74P-9E&feature=watch

Output should be : MrOiL74P-9E

I try to search and I found this function : 

function remove_query_part($url, $term)
{
    $query_str = parse_url($url, PHP_URL_QUERY);
    if ($frag = parse_url($url, PHP_URL_FRAGMENT)) {
        $frag = '#' . $frag;
    }
    parse_str($query_str, $query_arr);
    unset($query_arr[$term]);
    $new = '?' . http_build_query($query_arr) . $frag;
    return str_replace(strstr($url, '?'), $new, $url);
}

This function just remove one parameter and return the rest. Can anyone edit this function to return just the video ID and Ignore whatever else in the URL.

Not tested but you could try....

function remove_query_part($url, $term) { 

// get the query part of the string (i.e. after the '?')
$query_str = parse_url($url, PHP_URL_QUERY);
$queryItems = explode('&', $query_str); 

$item = array(); 
$itemArray = array();
foreach ($queryItems as $item) {
    $itemArray = explode('=', $item); 
if($item[0] == $term) {
    return $item[1]; 
}

} 

return false; 
}

Quick and dirty:

$url='http://www.youtube.com/watch?v=MrOiL74P-9E&feature=watch';

function test($url)
{
    $data=parse_url($url);

    if(!isset($data['query']))
    {
        return null;
    }
    else
    {
        $ex=explode('&', $data['query']);

        foreach($ex as $key => $val)
        {
            $param=explode('=', $val);

            if($param[0]=='v')
            {
                return $param[1];
                break;
            }
        }
    }
}

echo test($url);

$query_str = parse_url($url, PHP_URL_QUERY);
parse_str($query_str, $args);

print $args['v'];   // <- MrOiL74P-9E

I think you know how to put this into a function...
