PHP method to determine if an array exists within an array

Question

Is there a php array method that can tell me if an array has arrays as its values without doing a foreach loop?

Why do you want to avoid a foreach loop? Most likely an answer that involves a built-in function will do more work than you just creating a foreach loop to do this then toss it in a function. — Commander

print_r(array_filter($array, "is_array"));

You can use array_filter

$array = array(1,array(),2);
                     ^--------------- array in array

if(array_filter($array,"is_array"))
{
    // I found some arrays
}
