## Example

`

     mixed array_rand ( array $input [, int $num_req = 1 ] )

`

## Description

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

## Return Values

If you are picking only one entry, array_rand() returns the key for a random entry. Otherwise, it returns an array of keys for the random entries. This is done so that you can pick random keys as well as values out of the array.
