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.

Syntax

shuffle(array)

Example

 "Dog", "b" => "Cat", "c" => "Horse"); shuffle($my_array); print_r($my_array); ?>

Output:

Array ( [0] => Cat [1] => Horse [2] => Dog )
