php – 设置随机播放,不重复

我想要做的是在同一个网页上为大约十几个人创建这些卡片组,但我无法弄清楚的部分是如何制作它,这样每个完整的套装都是独一无二的,并且不会从给定的套装中重复对任何其他用户.

一个带有简短说明的简短代码示例对我最有帮助.

这是我根据自己的需要修改的代码.真的没什么变化.

if (empty($_POST)) {
for ($i = 1; $i < 16; $i++) {
    $numbers['ALL'][] = $i;
}

$picks = array();


$letters = array ('ALL');
foreach ($letters as $letter) {
    for ($i = 0;$i < 10;$i++) {
        shuffle($numbers[$letter]);
        $chunks = array_chunk($numbers[$letter],5);
        $cards[$i][$letter] = $chunks[0];
        if ($letter == 'N') {
            $cards[$i][$letter][2] = '  '; // Free Space
        }

    }
    foreach ($numbers[$letter] as $number) {
        $balls[] = $letter.$number;
