Php 从数组创建一个数组并保持相同的顺序

我制作了一副非常简单的卡片。我使用3个数组，$deck，$cards，&$used$牌组是场上的牌，$牌是比较数组，$使用是丢弃数组。当从$deck使用卡时，它们将在$used数组中占有一席之地。我的问题是，当它们被放置在$used数组中时，它们会按数字顺序排列。我不要这个。我需要它们的顺序与从$deck数组中移除它们的顺序相同。完整代码如下

<?php

/*
    This code creates a deck of cards and deals them
    It also creates a discard pile of used cards. It never
    deals duplicates and will re-shuffle the deck if it
    gets under 7 cards.
*/

dealCards();

/* 
    This function creates the deck of cards.
    It will deal out 5 cards and remove those
    5 cards from the deck.
*/

function dealCards() {

    // checks to see if a session has been created
    if (isset($_SESSION["deck"])) {
        $deck = $_SESSION["deck"];
    } else {    
    // if session has not been created it
        $deck = range(1, 52);
        shuffle($deck);
        $_SESSION["deck"] = $deck;
    }

    // comparison array. 
    $cards = range(1, 52);

// will use the same deck until it has 7 or less cards
if (count($deck) > 7) {

// deals 5 cards from the array $deck
    for ($i = 0; $i < 5; $i++) {

        print "<img src="/main/deck/$deck[$i].png" alt="Card: $deck[$i]" />";

        // removes dealt cards from the deck
        unset($deck[$i]);
        // clears empty values from the array
        $deck = array_values(array_filter($deck));
        // replaces session data with new deck
        $_SESSION["deck"] = $deck;
    }

} else {

    // shuffle the full 52 cards again if the deck is less than 7 cards
    $deck = range(1, 52);
    shuffle($deck);
    $_SESSION["deck"] = $deck;

}
    /*
        compares $deck to the comparison array $cards
        and places the differences in an array 
        called $used which then can be used as a discard
        pile.
    */
    $used = array_diff($cards, $deck);

    // testing purposes.
    print "<pre>";
    print_r ($deck);
    print "</pre>";

    print "<pre>";
    print_r ($used);
    print "</pre>";

}

我想到的第一件事是，当你解除你的甲板阵列

您可以将卡放入$used数组中

但这只是第一次奏效。在第二次使用dealCards时，它将被覆盖。 另外，$used数组中肯定会有一些空位置。

你需要永久保存吗？

我已经让它工作了。代码需要清理一下，但至少可以工作。谢谢瑞肯和其他人的帮助。下面是修改后的工作代码

如果需要将它们按相同顺序排列，请将数组也存储在会话中。在未设置$deck[$i]；，执行$_会话['used'][=$deck[$i]；。如果没有存储卡片使用顺序的地方，您永远无法以相同的顺序“重建”该精确数组。我尝试了您的建议，但它们仍然以数字顺序填充$used数组。然后，或者您正在使用它执行其他操作，从而导致重新排序。开箱即用，它的工作原理如链接代码所示。我让它工作了，但是它在$used数组中只保存了5张卡。每次交易它都会用新发的5张牌替换之前的5张牌。我试图将每一张牌都保留在$used中，直到牌组重新洗牌。您正在覆盖某处的$u会话['used']。这可能有两个主要原因：1一个逻辑错误，它确实在某处重置了$_会话['used']，2您可能已经启用了它，它在PHP 5.3.0中被弃用，在PHP 5.4.0中被删除。你在某处使用了一个$used变量。我只需要将它们删除并存储，直到$deck数组有7个或更少的值，在这一点上，整个函数都会重置。让我直截了当地说，如果你有这种1，4，6，9级丢弃的卡，$used数组应该是什么样子？假设前5张卡是95276，第二组5张卡是108431。生成$used数组时，它会按1 2 3 4 5的顺序下降。它们应按处理顺序存储。从2个手示例中，$used数组应该看起来像9 5 2 7 6 10 8 4 3 1那么为什么不直接使用array_push$used，$deck[$i]？

    // removes dealt cards from the deck
    unset($deck[$i]);

    // removes dealt cards from the deck then put them in the discard pile
    $used[$i] = $deck[$i];
