打乱数组 shuffle

<?php

　　$arr = range(,);

　　print_r($arr);

　　echo '<br />';

　　shuffle($arr);

　　print_r($arr);

?>

Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 )

Array ( [0] => 6 [1] => 1 [2] => 3 [3] => 2 [4] => 5 [5] => 7 [6] => 8 [7] => 4 )

如果是二维关联数组,也可用该方法
