The shuffle () function sorts the elements in the array in random order.

If yes, TRUE is returned. Otherwise, FALSE is returned.

Note: This function assigns a new key name to the cell in the array. This will delete the original key name, not just the reorder.

Note: Since PHP 4.2.0, the random number generator is no longer needed to be planted using the srand () or mt_srand () function, which has been automatically completed.

<? Php Tutorial
$ My_array = array ("a" => "Dog", "B" => "Cat", "c" => "Horse ");
Shuffle ($ my_array );
Print_r ($ my_array );
?>

);

// Random sorting of arrays
Shuffle ($ ads );
