multi dimensional array in random order

by

shuffle() is the way to go here. It prints 1 because shuffle changes the array in-place and returns a boolean, as it is written in the documentation:

Returns TRUE on success or FALSE on failure.

I suggest to also read the documentation of array_rand():

Picks one or more random entries out of an array, and returns the key (or keys) of the random entries.

Always read documentation if you use built-in functions. Don’t just assume how the work. I bet it took more time to write the question than looking this up.
