PHP: array_rand() function
PHP: Pick one or more random entries out of an array
The array_rand() function is used to fetch one or more random entries from an array. It uses a pseudo-random number generator that is not suitable for cryptographic purposes.

|no_rand_keys||No of entries to get.||Optional||Integer|
A random key if the value of no_rand_keys = 1.
If the value of no_rand_keys is greater than 1 it returns an array.
Value Type: Mixed*.
*Mixed : Mixed indicates multiple (but not necessarily all) types.
<?php $array1= array('Mathematics','Physics','Chemistry','Biology'); $rand_keys = array_rand($array1,2); echo $array1[$rand_keys] . "\n"; echo $array1[$rand_keys] . "\n"; ?>
