Question

Im starting to get no ideias to solve this or probably its more simples than i expecpt.
Hope someone can help:

Im try to verify if

array A

arrA = Array
(
    [0] => hindu
    [1] => inglês
)

exists in array B

arrb = Array
(
    [0] => active
    [1] => awsome
    [2] => speaker
    [3] => creative
    [4] => team leader
    [5] => project manager
    [6] => chinese
    [7] => hindu
    [8] => spanish
    [9] => english
) 

If(in_array($arrA , $arrB)){
echo true;
}

Meaning if the 2 elements of array A exist in Array B then return TRUE. ( Both elements not just one).
And the size of Array A is not always the same ( can have 1 to many elements).

I tryed in_array and various recursive functions, but no luck…

Anyone?

Thanks for the help in advance.

You can use array_diff() –

$all_elements_exist = count(array_diff($a, $b)) == 0 ? true : false;
