返回具有较少元素的数组的最短方法

I have two arrays. I wish to return the array containing fewer elements.

My code so far:

<?php

if ( count($a) < count($b) )
    return $a;
else
    return $b;

Thanks in Advance.

Your way of doing it is fine. You could use the ternary ? operator to create a shorter if statement though:

return (count($a)<count($b)) ? $a : $b;
