shuffle — Shuffle an array


bool shuffle ( array &$array )

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

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

Example#1 shuffle() example

srand((float)microtime() * 1000000);
foreach (
$numbers as $number) {
"$number ";

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.
