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:

$param = array(2, 3, 4, -2, -3, -5);

function positive_function($arr) {
    foreach ($arr as &$value) {
        if($value > 0)
            return $value;
    }
}

$modParam1 = positive_function($param);

var_dump($modParam1);

I think I have something wrong with the foreach statement, any sage advice here?

Answer 1

try:

$param = array(2, 3, 4, -2, -3, -5);

$positive = array_filter($param, function ($v) {
  return $v > 0;
});

print_r($positive);
