1.2.1097. Should Cache Local

Repeated calls to a method with the same arguments should be put in a local cache.

It speeds up processing, even in case of a simple property fetch. A local cache makes the code more readable and more compact.

<?php

function foo() {
     $goo = goo(), 0, 3;
     $a = strtolower($goo);
     $b = strtoupper($goo);

     return $a . '-' . $b;
}

function foo2() {
     $a = strtolower(goo(), 0, 3);
     $b = strtoupper(goo(), 0, 3);

     return $a . '-' . $b;
}

?>
