You need PHP 5.3 for that. Here's the RFC:

Hi.
Quite a simple question (assuming I've got the terminology correct).
Are there any plans to allow code like this (amended example taken
from the array_map() documentation) ...
<?php
$a = array(1, 2, 3, 4, 5);
$b = array_map(function($n){return($n * $n * $n)}, $a);
print_r($b);
For me, this is cleaner than having a use-once, namespace-polluting function.
Currently, this is producing a parse error.
A real alternative though would be to allow nested functions...
<?php
function cube_array($a) {
function cube($n) {
return($n * $n * $n);
}
return array_map("cube", $a);
}
$a = array(1, 2, 3, 4, 5);
$b = cube_array($a);
print_r($b);
Ideally, cube() would not be visible outside of cube_array(). Scoped functions.

Richard Quadling.
