shuffle

(PHP 4, PHP 5)

shuffleShuffle an array

Description

bool shuffle ( array &$array )

This function shuffles (randomizes the order of the elements in) an array.

Parameters

array

The array.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 shuffle() example

<?php
$numbers 
range(120);
srand((float)microtime() * 1000000);
shuffle($numbers);
foreach (
$numbers as $number) {
    echo 
"$number ";
}
?>

Notes

Note: This function assigns new keys to the elements in array . It will remove any existing keys that may have been assigned, rather than just reordering the keys.

Note: As of PHP 4.2.0, there is no need to seed the random number generator with srand() or mt_srand() as this is now done automatically.
