Перемешать заданный массив ⇐ Php

[Anonymous]

У меня есть облако тегов, которое в настоящее время настроено так, чтобы сначала отображался самый популярный элемент с использованием (строка 205):
// arsort($array_end);

который переворачивает массив. Если я оставлю это без внимания, список будет отображаться в алфавитном порядке.
Я бы хотел, чтобы результаты отображались в случайном порядке. Я думал о php-shuffle, но не знаю, как это сделать. Буду признателен, если кто-нибудь сможет мне помочь, спасибо!
См. php ниже:
