Checking if an array contains all elements of another array

Question

I\'m designing an electrical engineering application. However, i\'m stuck on this: I have the following array

Answer 1

Count the total of $GroupOfEight[$i]
Count the total of $myStack
if totals are equal:
In a loop -
if $myStack[$c] is in_array($GroupOfEight[$i]): $equal = 1
else $equal = 0; exit;

if $equal == 1 -> arrays are identical
