导读：我想做什么我有一个看起来像这样的数组 – Array([0] = Array ( [id] = 1 [date] = 23-09-2015 [name] = Public Transport [group_id] = 1 )[1] = Array ( [id] = 2 [date] = 23-09-2015 [name] = Parking [group_id] = 1 )[2] = Array ( [id] = 4 [date] =

我想做什么

我有一个看起来像这样的数组 –

Array
(
[0] => Array
    (
        [id] => 1
        [date] => 23-09-2015
        [name] => Public Transport
        [group_id] => 1
    )

[1] => Array
    (
        [id] => 2
        [date] => 23-09-2015
        [name] => Parking
        [group_id] => 1
    )

[2] => Array
    (
        [id] => 4
        [date] => 23-09-2015
        [name] => Food
        [group_id] => 2
    )

[3] => Array
    (
        [id] => 3
        [date] => 23-09-2015
        [name] => Fix
        [group_id] => 3
    )

[4] => Array
    (
        [id] => 4
        [date] => 23-09-2015
        [name] => Entertainment
        [group_id] => 3
    )

)

我想在表中列出它,根据组ID完成分组

该集团有交通运输[1],住宿[2]和津贴[3]. [4]未分组.

表结构需要如下所示.

ID| Date     | Name             |
  ---------------------------------
  ---------------------------------
  1 |23-09-2015|Public Transport
  2 |23-09-2015|Parking
  ---------------------------------
          TRANSPORTATION
  ---------------------------------
  3 |23-09-2015|Food
  ---------------------------------
          ACCOMMODATION
  ---------------------------------
  4 |23-09-2015|Fix
  ---------------------------------
          ALLOWANCE
  ---------------------------------
  5 |23-09-2015|Entertainment

你可以在这里看到id 1& 2个来自交通,3个住宿,4个住宿和娱乐没有团体.
如果任何组dosenot在数组中有数据,那么它应该显示NO DATA AVAILABLE

---------------------------------
  3 |23-09-2015|Food
  ---------------------------------
          ACCOMMODATION
  ---------------------------------
       No data available
  ---------------------------------
          ALLOWANCE
  ---------------------------------

我尝试了什么

<?php
     $j = 1;
     foreach ($summary as $list) {
        if ($j != $list['group_id']) {

             if ($j == 1) {
                   $group = 'Transportation';
             } else if ($j == 2) {
                    $group = 'Accomodation';
              } else if ($j == 3) {
                    $group = 'Allowances';
              } else {
                    $group = '';
              }
          ?>

                        <tr class="summary-title">
                            <td colspan="7"><?php echo $group; ?></td>
                        </tr>
                    <?php } ?>
      <tr>

           <td><?php echo $list['id']; ?></td>
           <td><?php echo $list['date']; ?></td>
           <td><?php echo $list['name']; ?></td>
      </tr>
        <?php
            $j = $list['group_id'];
        }
        ?>

数组按group_id按升序排序.组ID将始终具有值1,2,3,4.

我的代码有问题

它部分工作.但是当group_id数组中没有值时,我无法显示NO DATA AVAILABLE.此外,如果group_id = 4在数组中不可用,那么它不会在底部设置ALLOWANCE,因为数组循环在设置值之前完成.

解决方法

编辑：删除了整个页面,因为它现在变得混乱.

$summary = array();
$summary[] = array('id'=>1,'date'=>"23-09-2915",'name'=>"Public transpor1",'group_id'=> 1);
$summary[] = array('id'=>2,'date'=>"24-09-2915",'name'=>"Public transpor2",'group_id'=> 3);
$summary[] = array('id'=>3,'date'=>"25-09-2915",'name'=>"Public transpor3",'group_id'=> 1);
$summary[] = array('id'=>4,'date'=>"26-09-2915",'name'=>"Public transpor4",'group_id'=> 2);
$summary[] = array('id'=>5,'date'=>"27-09-2915",'name'=>"Public transpor5",'group_id'=> 1);
$newarray = array('Transportation'=>array(),'Accomodation'=>array(),'Allowances'=>array(),'Not found'=>array());
foreach ($summary as $list) {
    if(isset($list['group_id'])){
         $testid = $list['group_id'];
    }else{
         $testid = 4;
    }
    if ($testid  == 1) {
        $group = 'Transportation';
    } else if ($testid  == 2) {
        $group = 'Accomodation';
    } else if ($testid  == 3) {
        $group = 'Allowances';
    } else {
        $group = 'Not found';
    }
    $newarray[$group][] = $list;
}
echo "<table>";
foreach($newarray as $key => $array){
    echo "<tr><th>".$key."</th></tr>";
    if(count($array) > 0){
        foreach($array as $row){
            echo "<tr><td>".$row['name']."</td></tr>";
        }
    }else{
        echo "<tr><td>Not data</td></tr>";
    }
}
echo "</table>";

这应该做你想要的,但是认真的,付出一些努力lol.如果您对问题不太清楚,我将不会继续编辑它,直到它完成您想要的操作
