Answer 1

function in_multi_array($needle, $key, $haystack) 
{
    $in_multi_array = false;
    if (in_array($needle, $haystack))
    {
        $in_multi_array = true; 
    }else 
    {
       foreach( $haystack as $key1 => $val )
       {
           if(is_array($val)) 
           {
               if($this->in_multi_array($needle, $key, $val)) 
               {
                   $in_multi_array = true;
                   break;
               }
           }
        }
    }

    return $in_multi_array;
