PHP shuffle function

Definition and Usage

shuffle() function rearranges the elements in the array in random order.

If successful, return TRUE, otherwise return FALSE.

Note: This function assigns a new key name to the unit in the array. This will delete the original keys rather than just reorder them.

Note: As of PHP 4.2.0, it is no longer necessary to seed the random number generator with the srand() or mt_srand() function, it is now done automatically.
