Using some of php's built in array functions to do something a little similar to erlang's list comprehensions.

listcomprehension.php

<?php
$a = array(1, 2, 3, 4, 5);

$f = function($a) { return (($a * 2));};

$b = array_values(array_map($f, array_filter($a, function($a) {return ($a > 2);})));

var_dump($b);
