Now with php array_map function you can apply a  function to all values in array on one go

here is an example

<?php
function cube($n)
{
return($n * $n * $n);
}

$a = array(1, 2, 3, 4, 5);
$b = array_map("cube", $a);
print_r($b);
?>

Result will be like this

Array
(
    [0] => 1
    [1] => 8
    [2] => 27
    [3] => 64
    [4] => 125
)
