Sorting an array to match the order of values of another array

I'm running hundreds of curl operations in parallel to my own API, the response array that I get is out of order ( the reason being that the first one to finish gets added to the response array first). I need to sort these back so they correspond to the input array, in order to do that I have already written a function as shown below, I'm interested if there is a more efficient way to do this or not.

Note : The sample shows what I mean, however the input array is usually more than 100 elements long.

Sample Input :

$input = array (
   'http://www.yandex.ru',
   'http://www.mail.ru',
   'http://www.google.com'
)

Response :

$response = array (
    array('http://www.mail.ru', 200, 'some other string'),
    array('http://www.yandex.ru', 200, 'some string'),
    array('http://www.google.com', 200, 'yet another string')
)  

Function :

function re_order($original, $scrambled) {
    foreach ($scrambled as $url_response) {
       $key = array_search($url_response[0],$original);
       $result[$key] = $url_response;
    }
    ksort($result);
    return $result;
}

Resulting array after calling the function (i.e. desired result).

$result = array (
    array('http://www.yandex.ru', 200, 'some string'),
    array('http://www.mail.ru', 200, 'some other string'),
    array('http://www.google.com', 200, 'yet another string')
)
