Remove items from array without looping

Question

Is there a way to eliminate more than one items from array without looping through it ?

Eg: array(1,3,67, 78, 60 , 5, 34, 68);

I want to remove items > 50 at once

Because when there are many items, it will slow down the process — Shaolin

It would require thousands if not more to slow your process. — Stijn Bernards

Sure, you can use array_filter:

$array = array_filter(array(1, 3, 67, 78, 60 , 5, 34, 68), function($element) {
                                                              return $element <= 50;
                                                           });

The callback function must return true for those items in the array that you want to keep.

This is not possible to do without looping, however you can use array_filter() function in order to hide the loop

function remove($var) { return $var < 50; }
$data = array_filter($data, 'remove');
