显示和随机化PHP阵列

我有一个数组显示如下结果:

Array
(
    [0] => 71
    [1] => 56
    [2] => 64
    [3] => 82
    [4] => 90
    [5] => 80
    [6] => 65
    [7] => 62
    [8] => 14
    [9] => 3
)

我的代码是:

while($row = mysql_fetch_assoc($result))
{   

  $show[] = $row['number'];

}
   echo '
'; print_r($show);


如何随机化数组内容并将其显示为仅5位数e:g 71 64 14 80 82
