Try something like this:

function selectByIdOrURL($array, $data) {
    foreach($array as $row) {
       if($row['unique_id'] == $data || $row['url'] == $data) return $row;
    }
    return NULL;
}

$array = array(
           array('unique_id' => 5, 'url' => 'http://blah.com'),
           array('unique_id' => 3, 'url' => 'http://somewhere_else.com')
         );
$found = selectByIdOrURL($array, 5); //array('unique_id' => 5, 'url' => 'http://blah.com')
$nfound = selectByIdOrURL($array, 10); //NULL
