multi dimensional array in random order

Question

I want to make it so that my multi dimensional array is in a random order. How would you do it?

// This is how the array looks like
print_r($slides);

Array
         


        

Answer 1

It works perfect. print_r(shuffle($slides))) gives the output of TRUE, since the return value of shuffle is a boolean and not an array.

See the working example here: http://codepad.org/B5SlcjGf

Answer 2

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.

Answer 3

i am not sure how you want it to display but you can loop the array and use php rand(0,arraylen) function to parse the array.

Answer 4

Instead of

print_r(shuffle($slides));

do

shuffle($slides);
print_r($slides);

You see shuffle() shuffles the array in-place
