How can I mix up the order of values in an array?

Sir,

How can I mix up the order of values in an array?

Hi..
We can use shuffle() function to randomizes the order of the elements & values in the array.

This function assigns new keys for the elements in the array. Existing keys will be removed.

This function returns TRUE on success, or FALSE on failure.

Example:

<?php
$my_array = array("a" => "Dog", "b" => "Cat", "c" => "Horse");

shuffle($my_array);
print_r($my_array);
?>

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

hi sheetal panday,

A simple way to achieve the result of mixing up the values in an array is to use the shuffle function, which takes the name of the array you want to randomise. Here is a code snippet to demonstrate the shuffle function in action:

<?php
$values = range("A","Z");
shuffle($values);
print_r($values);
?>

This will print something like the below, shuffling up the letters of the alphabet:

Array
(
[0] => J
[1] => R
[2] => C
[3] => W
[4] => Y
[5] => L
[6] => B
[7] => A
[8] => P
[9] => O
[10] => M
[11] => V
[12] => D
[13] => X
[14] => F
[15] => S
[16] => Q
[17] => G
[18] => I
[19] => H
[20] => N
[21] => Z
[22] => U
[23] => E
[24] => K
[25] => T
