PHP: how to check for value from array A in array B w/out loop
<p>Two associative arrays A and B: how do I check if any value of from array A exists in array B without a foreach or any other loop? </p>

<p>Is this possible?</p>

<p>There is array_key_exists and in_array but they search for values in an array, not values from an array in another array.</p>

<p>Hope this makes some kind of sense :)</p>
