Copy PHP Array where elements are positive

Question

trying to transfer one array with a combination of positive and negative numbers to a new array- but only where the elements are positive.

This is what I have so far:

Answer 1

Your function just returned the first positive value.

You have to create a new array, to hold all the positive values and return this array, after the foreach loop run through all values.

function positive_function($arr) {
    $result = array();

    foreach ($arr as &$value) {
        if($value > 0) {
          $result[] = value;
        }
    }

    return $result;
}

Another option would be to apply a mapping function like shown by @Yoshi. This depends, whether you need to keep the old array or just want to modify it by deleting all not-positive values.
