This function shuffles (randomizes the order of the elements in) an array. It uses a pseudo random number generator that is not suitable for cryptographic purposes.
Returns true on success or false on failure.
This function assigns new keys to the elements in array. It will remove any existing keys that may have been assigned, rather than just reordering the keys.
Resets array's internal pointer to the first element.
|7.1.0||The internal randomization algorithm has been changed to use the Mersenne Twister Random Number Generator instead of the libc rand function.|
