Why not using arithmetic approach like this:

function reverseNum(int $n, int $i = 0)
{
return ($n === 0) ? $i : reverseNum($n/10, $i*10 + $n%10);
}
Even if U want to use string, then why are U using so many heap with strrev() function, why not just return result with cast?

function reverseNum($num)
{
return (int)strrev($num);
}
