Does Array 'All' Contain All Elements from Array 'Search This'?

Is Array 'All' Inclusive of Array 'Search This'?

The task at hand is to determine whether an array named 'all' contains all the elements of another array named 'search_this'. A simple and efficient way to approach this is by using array_diff, as demonstrated below:

<code class="php">$containsAllValues = !array_diff($search_this, $all);</code>
Copy after login

This code utilizes array_diff to identify the difference between $search_this and $all. If the resulting array is empty (indicating no differences), it signifies that $all contains all the values in $search_this. To account for this, a logical negation (!) is applied to ensure the result is true when $all is fully inclusive and false otherwise.

This approach avoids redundant computations and unnecessary object creation, resulting in a concise and efficient solution to the given problem.
