Question

我有四个不同的阵列，每个阵列都有不同的长度。我想以下列方式遍历每个数组。（注意：为了便于使用，我只在每个数组中包含少量值，无论数组的长度如何，解决方案都必须正常工作。）

$array1 = ["A","B","C"];
$array2 = ["D","E","F","G","H"];
$array3 = ["I","J","K","L","M"];
$array4 = ["N","O","P","Q"];

$combinedArray = [];

我需要$ combinedArray中的每个值包含一个唯一的字符串，该字符串由每个数组中的一个元素组成。 $ combinedArray应该具有与可能的唯一变体一样多的值。因此，使用上面的示例，$ combinedArray中应该有300（3 * 5 * 5 * 4）个值。

因此$ combinedArray中的每个值应类似于以下内容：

$combinedArray[0] = "ADIN";
$combinedArray[1] = "BDIN";
$combinedArray[2] = "CDIN";
$combinedArray[3] = "AEIN";
...
$combinedArray[MAX] = "CHMQ";

有关如何做到这一点的任何想法？感谢。

试试这个： -

$array1 = ["A","B","C"];
$array2 = ["D","E","F","G","H"];
$array3 = ["I","J","K","L","M"];
$array4 = ["N","O","P","Q"];

$combinedArray = [];

foreach ($array1 as $a1){
    foreach ($array2 as $a2){
        foreach ($array3 as $a3){
            foreach ($array4 as $a4){
                $combinedArray[] = $a1 . $a2 . $a3 . $a4;
            }
        }
    }
}

没什么特别的。刚刚嵌套的循环。希望这会有所帮助。

循环并附加PHP中多个数组的字符串
