Anonymous functions, also known as closures, allow the creation of functions which have no specified name. They are most useful as the value of callback parameters, but they have many other uses.

Example #1 Anonymous function example

<?php
echo preg_replace_callback('~-([a-z])~', function ($match) {
return strtoupper($match[1]);
}, 'hello-world');
// outputs helloWorld
?>

Note: It is possible to use func_num_args(), func_get_arg(), and func_get_args() from within a closure.

The Closure class (PHP 5 >= 5.3.0) used to represent anonymous functions.
