Checking if the array contains same type variables like all numeric in php

I was in need of checking if the given array is all numeric or not. A colleague suggested with snippet the use of array_reduce – here the implementation

$numbers = array(1,22, 7, 34, 20);
$all_numbers = array_reduce($numbers, function($val1, $val2){
   return $val1 && is_numeric($val2);
}, TRUE);

Should do the trick.
