【问题描述】：

我正在研究 PHP 中的关联数组。在这里，我制作了一个多重关联数组。我想以表格形式显示我的数组。数组是

<?php

$schoolDetails = array(
    //First School Details
    array(
        
        array("schoolName" => "TCS"),


        array(
            "branchName"       => "Iqbal Campus",
            "phone"            => "052-4667281",
            "numberofTeachers" => 51
        ),

        array(
            "departmentName" => "Maths",
            "HOD"            => "Mr Ali"
        ),
        array(
            "departmentName" => "Science",
            "HOD"            => "Mr Imran"
        )

    ),
    array(

        array("schoolName" => "CSS"),
        array(
            "branchName"       => "Gohdpur Campus",
            "phone"            => "052-4667281",
            "numberofTeachers" => 20
        ),
        array(
            "departmentName" => "Chemistry",
            "HOD"            => "Mr Abdullah"
        ),
        array(
            "departmentName" => "Computer",
            "HOD"            => "Mr Naeem"
        )

    ),

);

我尝试显示数据的方式如下：

  <table class="table table-bordered" id="dataTable" width="100%" cellspacing="0">
                                        <thead>
                                            <tr>
                                                <th>School Name</th>
                                                <th>Branch Name</th>
                                                <th>Phone Number</th>
                                                <th>Number of Teachers</th>
                                                <th>Department Name</th>
                                                <th>HOD</th>
                                            </tr>
                                        </thead>
                                        <tfoot>
                                            <tr>
                                            <th>School Name</th>
                                                <th>Branch Name</th>
                                                <th>Phone Number</th>
                                                <th>Number of Teachers</th>
                                                <th>Department Name</th>
                                                <th>HOD</th>
                                            </tr>
                                        </tfoot>
                                        <tbody>
                                            <?php  foreach ($schoolDetails as $school) {
                                                    foreach ($school as $schools) {
                                                        foreach ($schools as $key => $value) {?>
                                            <tr>
                                                            <td><?php echo $value; ?></td>
                                            </tr>
                                            <?php }}}?>

        
                                        </tbody>
                                    </table>

但我没有在正确的行和列中得到结果。那么我应该怎么做才能以精确的表格形式显示它，因为我从未经历过这种任务。

【解决方案1】：

foreach($schoolDetails as $schoolDetail) {
    echo "<tr>";
    echo "<td>{$schoolDetail[0]["schoolName"]}</td>";
    echo "<td>{$schoolDetail[1]["branchName"]}</td>";
    echo "<td>{$schoolDetail[1]["phone"]}</td>";
    echo "<td>{$schoolDetail[1]["numberofTeachers"]}</td>";

    if(!empty($schoolDetail[3]['departmentName'])) {

        echo "<td>{$schoolDetail[2]["departmentName"]}" . ", " . "{$schoolDetail[3]["departmentName"]}</td>"; 

    } else {

        echo "<td>{$schoolDetail[2]["departmentName"]}</td>";

    }

    if(!empty($schoolDetail[3]['HOD'])) {

        echo "<td>{$schoolDetail[2]["HOD"]}" . ", " . "{$schoolDetail[3]["HOD"]}</td>"; 

    } else {

        echo "<td>{$schoolDetail[2]["HOD"]}</td>"; 
    
    }

    echo "</tr>";
}

首先，您似乎在新行而不是新列中添加值：

<tr>
    <td><?php echo $value; ?></td>
</tr>

<tr>tags 添加新的表格行。它们应该添加到最后一个循环之外。

下一个问题是每所学校的值比表格列的数量多。每所学校都有一个以上的部门。应该如何在表格中显示？

<?php
 foreach ($schoolDetails as $school) {
     echo "<tr>";
     echo "<td>{$school[0]["Schoolname"]}</td>";
     echo "<td>{$school[1]["branchName"]}</td>";
     echo "<td>{$school[1]["phone"]}</td>";
     echo "<td>{$school[1]["numberofTeachers"]}</td>";
     echo "<td>{$school[2]["departmentName"]}</td>";
     echo "<td>{$school[2]["HOD"]}</td>"; 
     echo "</tr>";
 }

但是，上面的代码只会列出第一个部门...您需要提供有关如何显示其余部分的更多信息...

【讨论】：

它缺少$school[3] 数据。 departmentName 大于 1，而不是 FIT 这个
我希望所有的部门都被列出来反对它的学校。例如 TCS 是学校名称，因此它必须显示其所有相关部门和部门的相关教师。

@Gowire 答案只是修改。

 foreach ($schoolDetails as $school) {
     echo "<tr>";
     echo "<td>{$school[0]["schoolName"]}</td>";
     echo "<td>{$school[1]["branchName"]}</td>";
     echo "<td>{$school[1]["phone"]}</td>";
     echo "<td>{$school[1]["numberofTeachers"]}</td>";
     echo "<td>{$school[2]["departmentName"]}</td>";
     echo "<td>{$school[2]["HOD"]}</td>"; 
     echo "</tr>";
     for($i=3;$i<=5;$i++){
        if(isset($school[$i])){
             echo "<tr>";
             echo "<td></td>";
             echo "<td></td>";
             echo "<td></td>";
             echo "<td></td>";
             echo "<td>{$school[$i]["departmentName"]}</td>";
             echo "<td>{$school[$i]["HOD"]}</td>"; 
             echo "</tr>"; 
        }
     }
 }
