Shuffle given array - php

Question

I have this tag cloud, which is currently set to show the most popular item first with the use of (line 205):
// arsort($array_end);
which reverses the array. If i leave this out it shows the list alphabetically.
I would like to have the results shown randomly. I thought of php-shuffle, but i don't know how to go about it. Appreciate if someone could help me out here, Cheers!

Answer 1

Use the shuffle function:
This function shuffles (randomizes the order of the elements in) an array.
A little below
// arsort($array_end);`
You got this code:
foreach ($array_end as $key => $value)
{
Replace it with this:
$array_end_keys = array_keys($array_end);
shuffle($array_end_keys);
foreach ($array_end_keys as $key)
{
$value = $array_end[$key];
