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

You can try :

$searchKeys = array();
foreach ( $GroupOfEight as $key => $values ) {
    (count(array_intersect($values, $myStack)) == count($myStack)) and $searchKeys[] = $key;
}

#Output all keys it found same match
var_dump($searchKeys);

#OR Output Each Array it found a match
foreach($searchKeys as $key)
{
    var_dump($GroupOfEight[$key]);
}
