php在多个数组中循环

我有一个表格，有7个不同的标准。每个标准有3或4个问题，用户将检查相应的值

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

我想循环处理每个问题，并创建一个字符串，其中包含条件id->问题id->和答案值

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

我似乎无法让它工作

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

以下是阵列的转储：

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

标准数组：

array(7) { [0]=> string(1) "1" [1]=> string(1) "3" [2]=> string(1) "5" [3]=> string(1) "7" [4]=> string(2) "10" [5]=> string(2) "11" [6]=> string(2) "12" } 

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

与每个问题关联的标准id

array(19) { [0]=> string(1) "1" [1]=> string(1) "1" [2]=> string(1) "1" [3]=> string(1) "3" [4]=> string(1) "3" [5]=> string(1) "3" [6]=> string(1) "5" [7]=> string(1) "5" [8]=> string(1) "5" [9]=> string(1) "7" [10]=> string(1) "7" [11]=> string(1) "7" [12]=> string(1) "7" [13]=> string(2) "10" [14]=> string(2) "10" [15]=> string(2) "10" [16]=> string(2) "11" [17]=> string(2) "11" [18]=> string(2) "11" }

下面是我的循环代码，它似乎不起作用：

                  $criteriaNums = $_POST['criteriaNum'];
              $fk_criterias = $_POST['fk_criteria'];
              $questionValue = $_POST['questionValue'];

              foreach($questionValue as $question => $answer){
                //echo $question;
                    foreach($fk_criterias as $fk){
                        foreach($criteriaNums as $crit){
                            if($fk == $crit){
                                $string1 = $fk;
                                //echo $string1;
                            }
                        }
                    }
                    $string2 = $question;
                    foreach ( $answer as $result ){
                      $string3 = $result;
                      //echo $string3;
                  }
                $criteria .= $string1 . '|' . $string2 . '|' . $string3 . '|';
                //echo $criteria;
              }

        [12] => Array

字符串2和3似乎工作正常。是string1不起作用

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array

                [0] => 5

        [16] => Array
            (
                [0] => 5
            )

    )

这是上述代码生成的输出：

        [12] => Array

            )

上面的条件id数组转储是与每个问题相关联的条件。如果您查看转储，您可以看到前6个（0-5）有1、1、1、3、3、3

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

[3] => Array
    (
        [14] => Array
            (

        [15] => Array

您能提供输出吗？您能提供一个输入阵列的示例吗？执行

$string1

的部分看起来正常，如果没有上述数据，则问题可能会得到解决

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

这个看起来很奇怪：

        [12] => Array
            (
                [0] => 5
            )

        [13] => Array
            (
                [0] => 5
            )

    )

[3] => Array
    (
        [14] => Array
            (
                [0] => 5
            )

        [15] => Array
            (
                [0] => 5
            )

        [16] => Array
            (
                [0] => 5
            )

    )

foreach ( $answer as $result ){
                      $string3 = $result;
                      //echo $string3;
                  }

您可能想要添加一个条件（如在条件中）或执行

$string3.=$result；

我修复了该问题：

    )

    (

            (

我已经将输出添加到原始问题中，您是否也可以提供输入数据？（+可能是手工制作的输入预期输出）我已经添加了输入。我还不确定，该标准用于什么？无论如何，我认为最好将fk_标准和标准化为单个关联数组（其中键是问题id，值是标准NUM的数组）。我越来越接近了。我将$_POST设置为三维数组，并包含了标准id。我添加了数组转储和输出。现在唯一的问题是它在嵌套循环内回音良好。它只回音循环外的最后一个值。
