Shuffle given array
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!
