shuffle
(PHP 4, PHP 5)
shuffle — Shuffle an array
Description
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
<?php
$numbers = range(1, 20);
srand((float)microtime() * 1000000);
shuffle($numbers);
foreach ($numbers as $number) {
echo "$number ";
}
?>
Note: Από την PHP 4.2.0, δεν είναι ανάγκη να κάνετε seed την γεννήτρια τυχαίων αριθμών με την srand() ή την mt_srand() αφού τώρα αυτό γίνεται αυτόματα.
