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

What you are looking for is a filter on your array (http://www.php.net/manual/en/function.array-filter.php)

This will remove the values in the array that do not furfill your needs. A basic example would be:

function is_positive($number) {
  return is_numeric($number) && $number >= 0;
}

$values = array(1, 5, -4, 2, -1);
$result = array_filter($values, 'is_positive');
print_r($result);

-- Why your function does not work:

You are returning a value. Inside a function a return will stop, because the answer is found. Thus returning the first positive number it finds in the array.
