Question

我有一个闪存卡阵列，并使用 shuffle 我输出15张独特的卡片，每张卡片有3张不同的卡片。

我想要做的是在同一个网页上为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，因此每个完整的设置都是独一无二的，不会重复给任何其他用户的一套。

简短说明的简短代码示例对我最有帮助。

这是我根据需要修改的代码。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;
    }
    shuffle($balls);
}

$cardsstr = serialize($cards);
$ballsstr = serialize($balls);
$picksstr = serialize($picks);

} else {
$cards = unserialize($_POST['cardsstr']);
$balls = unserialize($_POST['ballsstr']);
$picks = unserialize($_POST['picksstr']);
array_unshift($picks, array_shift($balls));

echo "<h1>Just Picked: " . $picks[0] . "</h1>";

$cardsstr = serialize($cards);
$ballsstr = serialize($balls);
$picksstr = serialize($picks);
}

Picks : <?php echo implode(',', $picks) ?>

由于每个集合中有更多选项，因此随机选择足以实现唯一的最终结果。我的意思是不要让这件事变得更复杂。

试试这个样本

<?php
//Initialize your 5 sets here
$numbers['B'] = range(1,15);
$numbers['I'] = range(16,30);
$numbers['N'] = range(31,45);
$numbers['G'] = range(45,60);
$numbers['O'] = range(61,75);

//My Assumption is you to pick 3 from each 

while(TRUE){
 $rand = rand(0,5);
 if(count($numbers_B) < 3 && !in_array($numbers['B'][$rand]){
   $numbers_B[] = $numbers['B'][$rand];
 }

 $rand = rand(0,5);
 if(count($numbers_I) < 3 && !in_array($numbers['I'][$rand]){
   $numbers_I[] = $numbers['I'][$rand];
 }
 $rand = rand(0,5);
 if(count($numbers_N) < 3 && !in_array($numbers['N'][$rand]){
   $numbers_N[] = $numbers['N'][$rand];
 }
 $rand = rand(0,5);
 if(count($numbers_G) < 3 && !in_array($numbers['G'][$rand]){
   $numbers_G[] = $numbers['G'][$rand];
 }
 $rand = rand(0,5);
 if(count($numbers_O) < 3 && !in_array($numbers['O'][$rand]){
   $numbers_O[] = $numbers['O'][$rand];
 }

if( count($numbers_B) == 3 && count($numbers_I) == 3 && count($numbers_N) == 3 && 

count($numbers_G) == 3 && count($numbers_O) == 3 ){
  break;
 }
    }
    $result = $numbers_B + $numbers_I + $numbers_N + $numbers_G + $numbers_O; ?>

这里$ result值应该是唯一的，我认为集合的数量是不变的。如果它是动态的，那么尝试使用二维数组的相同逻辑。

Answer 2

只需将准备好的集合存储在一个数组中，然后使用has（in_array函数）检查每个shuffle是否存在于数组中，如果它存在则再次进行洗牌。

设置随机播放，不重复
