Foreach 循环打印到许多值

Question

更新，解决

我有以下 2 个数组（长度相同），我想在表格中显示这些值。问题是他只打印我的第一个数组 ($gPositionStudents) 而不是数组 $gPositionInternships 的值。 目标是将每个学生与不同的实习联系起来，但我知道这两个数组之间没有关系。我正在寻找一个可以移动这两个数组的函数，这样每次我移动学生都有另一个实习机会。

重要的是要知道，我对数组 $gStartPositionInternship 做了一个小修改，我使这个数组的大小与数组 $gStartPositionStudents 的长度相等。使用以下代码： enter code here// 使 $gStartPositionInternships 中的项目只要数组 $gStartPositionStudents $gStartPositionInternships = array_pad($internships, $lengthStudentArray, 'null');

我包括了我当前的输出，见图：

enter code here// Make table
$header = array();
$header[] = array('data' => 'Internship');
$header[] = array('data' => 'UGentID');
// this big array will contains all rows
// global variables.
global $gStartPositionStudents;
global $gStartPositionInternships;
$rows = array();
foreach($gStartPositionStudents as $value) {
    foreach($gStartPositionInternships as $key=>$value2) {
        // each loop will add a row here.
        $row = array();
        // build the row
        $row[] = array('data' => $value[0]['value']);
        $row[] = array('data' => $value2);
    }
    // add the row to the "big row data (contains all rows)
    $rows[] = array('data' => $row);
}
$output = theme('table', $header, $rows);
return $output;

Answer 1

$rows[] 赋值在嵌套循环内 - 我看起来很可疑。尝试将该赋值放在嵌套循环之后，如下所示：

foreach($studentUGentID as $key=>$value) {
    foreach($internshipNaam as $key2=>$value2) {
    ...
    }
    // add the row to the "big row data (contains all rows)
    $rows[] = array('data' => $row);
}

Answer 2

您的原始数组是否按预期填充？尝试 print_f 找出答案。据我所知，如果您的原始数组同时包含 2 个条目，您应该得到一个 4 个条目数组，其中包含：

$rows = array(
    [0] => array(
        'data' => array(
            [0] => array(
                'data' => value
            ),
            [1] => array(
                'data' => value
            )
    ),
    [1] => array(
        'data' => array(
            [0] => array(
                'data' => value
            ),
            [1] => array(
                'data' => value
            )
    ),
    [2] => array(
        'data' => array(
            [0] => array(
                'data' => value
            ),
            [1] => array(
                'data' => value
            )
    ),
    [3] => array(
        'data' => array(
            [0] => array(
                'data' => value
            ),
            [1] => array(
                'data' => value
            )
        )
    )
)

这真的是你所期望的吗？
