Anonymous functions pre PHP 5.3.0

Hello,

How could I do

$ar = array_filter($ar, function($el) {
    $search = 'New York';
    $name = $ar['name'];
    $potentialNumber = substr($name, strlen($search));
    return ((substr($name, 0, strlen($search)) == $search) && // starts with NY
            ($potentialNumber == '' || is_numeric($potentialNumber)); // [0-9]*
});

Before PHP 5.3?

Answer 1

Closest would be to use create_function to mimic lambda functions http://php.net/manual/en/function.create-function.php
