<?php $input = array(1, 2, 3, 4, 5, 6); // Creates a new anonymous function and assigns it to a variable $filter_even = function($item) { return ($item % 2) == 0; }; // Built-in array_filter accepts both the data and the function $output = array_filter($input, $filter_even); // The function doesn't need to be assigned to a variable. This is valid too: $output = array_filter($input, function($item) { return ($item % 2) == 0; }); print_r($output);
