Using the array_rand(array $input [, int $num_req ] ) function we can get randomized selected elements from our array. The first parameter is our array. The second parameter is the number of elements we request. If we request one element only, array_rand() returns the key for the random element. If we request more than one element, array_rand() returns an array of keys for the random elements.
