you could loop from one of the arrays, check if abc from array1 is in array2. If true, check the values. — chepe263

Please try this code - I hope it helpes some way :

$matches = array();

for($i2 = 0; $i2 < count($Array2); $i2++)
{
    for($i1 = 0; $i1 < count($Array1); $i1++)
    {
        $bMatch = TRUE;
        foreach($Array1[$i1] as $key => $val)
        {
            if($Array2[$i2][$key] !== $val)
            {
                $bMatch = FALSE;
                break;
            }
        }
        if($bMatch)
        {
            $matches[] = array($i2, $i1);
        }
    }
}

It iterates through both arrays, comparing elements (which in fact are sub arrays) in such way that they are equal only if all elements of sub array from $Array2 are equal to all elements of sub array from $Array1. If the match is found, the pair ($i2, $i1) is added to the $matches array, so in the end, basing on your example, you would have something like:

$matches => array  (
               [0] => array (0, 0)
               ...
            )

I hope the assumption made is the proper one.
