What is diff between srand & shuffle?

Seeds the random number generator with seed..the seed becomes optional and defaults to a random value if omitted.



What is random number?

A random number is a number generated by a process, whose outcome is unpredictable, and which cannot be subsequentially reliably reproduced.

Shuffle

This function shuffles (randomizes the order of the elements in) an array.

This function assigns new keys for the elements in array. It will remove any
existing keys you may have assigned, rather than just reordering the keys.
