在codeigniter中查看多维数组

我的模型中有以下数组,这里是var_dump:

array(4) {
[0]=>
 array(1) {
   [0]=>
   array(5) {
 ["payment_student"]=>
 string(4) "2406"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(17) "Transport, 120 , "
 ["payment_amount"]=>
 string(3) "120"
   }
 }
 [1]=>
 array(1) {
   [0]=>
   array(5) {
     ["payment_student"]=>
 string(4) "2415"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(33) "Transport, 1500 , Tuition, 620 , "
 ["payment_amount"]=>
 string(4) "2120"
   }
     }
 [2]=>
     array(1) {
   [0]=>
   array(5) {
     ["payment_student"]=>
 string(4) "2175"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(17) "Transport, 620 , "
 ["payment_amount"]=>
 string(3) "620"
   }
 }
 [3]=>
 array(1) {
   [0]=>
   array(5) {
 ["payment_student"]=>
 string(4) "2087"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(33) "Transport, 1500 , Tuition, 420 , "
 ["payment_amount"]=>
 string(4) "1920"
   }
 }
}

这是我对循环的看法:

$i=0;
foreach ($payments_view as $key => $data) { 

            ?>
                <td><?php echo $i; ?></td>
                <td><?php echo $data[$i]['payment_student']?></td>
                <td><?php echo $data[$i]['arrears']?></td>

                <td><?php echo $data[$i]['payment_description']; ?></td>
                <td><?php echo $data[$i]['payment_amount']+$data[$i]['arrears']; ?></td>
                <td></td>
                <td></td>
                <td></td>
            </tr>
            <?php
                $i++;
 } 

显示第1行,但是对于下一行,会出现以下错误:

  

遇到PHP错误   严重性:注意   消息:未定义的偏移量:1   文件名:views / fee_register_list.php   行号:95   回溯:   文件:C:\ xampp \ htdocs \ learn_ci \ ksi_gentelella \ application \ views \ fee_register_list.php   行:95   功能:_error_handler   文件:C:\ xampp \ htdocs \ learn_ci \ ksi_gentelella \ application \ controllers \ Fee_Controller.php   行:173   功能:查看   文件:C:\ xampp \ htdocs \ learn_ci \ ksi_gentelella \ index.php   行:315   功能:require_once

如何将我的数组简单化为一个数组,以便能够使用它。在这种形状中,我认为它非常复杂。

试试这个:

for($i=0;$i<count($data);$i++){
   <tr>
   $firstObj=$data[i][0];
    for($j=0;$j<5;$j++){
       <td><?php echo $i; ?></td>
       <td><?php echo $firstObj[$j]['payment_student']?></td>
       <td><?php echo $firstObj[$j]['arrears']?></td>
       <td><?php echo $firstObj[$j]['payment_description']; ?></td>
       <td><?php echo $firstObj[$j]['payment_amount']." ".$firstObj[$j]['arrears']; ?></td>
    }
   </tr>
}

您可以使用array_column来“扁平化”您的阵列:

<?php foreach (array_column($payments_view, 0) as $i => $data) { ?>
    <tr>
        <td><?= $i; ?></td>
        <td><?= $data['payment_student']?></td>
        <td><?= $data['arrears']?></td>
        <td><?= $data['payment_description']; ?></td>
        <td><?= $data['payment_amount'] + $data['arrears']; ?></td>
        <td></td>
        <td></td>
        <td></td>
    </tr>
<?php } ?>

虽然不应该在视野中完成。尝试重构代码,这样您的视图就会以适当的格式显示数据。
