I wrote this function to check key in array and also check value if it exists...

function in_array_key($key, $array, $value = false)
{
    while(list($k, $v) = each($array))
    {
        if($key == $k)
        {
            if($value && $value == $v)
                return true;
            elseif($value && $value != $v)
                return false;
            else
                return true;
        }
    }
    return false;
}

.. very helpful function ...
