在foreach循环中插入一个空行

Question

我有一个php循环如下：

<?php foreach ($dcr_all as $key=>$d):?>

  <tr>
        <td><?php echo $key+1?></td>     

        <td >
          <?php $date_in = $d['DailyCallReport']['datetime_in'];
                 $date_in = new DateTime($date_in);
                 echo $date_in = $date_in -> format('h:i a');
           ?>
        </td>
  </tr>        

<?php  endforeach;?>

我的问题是，如果两行之间的时差($date_in)大于1小时，如何在当前行和上一行之间插入空白行。

这是数组：

Array
(
    [0] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 02:00:00
                )

        )

    [1] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 02:11:00
                )

        )

    [2] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 02:23:00
                )

        )

    [3] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 04:00:00
                )

        )

    [4] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 04:12:00
                )

        )

    [5] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 06:00:00
                )

        )

    [6] => Array
        (
            [DailyCallReport] => Array
                (
                    [datetime_in] => 2016-02-25 06:09:00
                )

        )

) 

这是我的表的图像..在第3行和第4行中，它们之间的时间差超过1小时，所以我只想显示一个空白行，其中包含没有索引号的消息.. < / p>

试试这样：

<?php
$dcr_all = Array
(
    0 => array (
    'DailyCallReport' => Array
            (
                'datetime_in' => '2016-02-25 02:00:00'
            )

    ),


1 => Array
    (
        'DailyCallReport' => Array
            (
                'datetime_in' => '2016-02-25 02:11:00'
            )

    ),

2 => Array
    (
        'DailyCallReport' => Array
            (
                'datetime_in' => '2016-02-25 02:23:00'
            )

    ),

3 => Array
    (
        'DailyCallReport' => Array
            (
                'datetime_in' => '2016-02-25 04:00:00'
            )

    )
 ); 


 $date_in = '';
 foreach ($dcr_all as $key=>$d):
    if($date_in != $d['DailyCallReport']['datetime_in']){
      if($date_in == ''){
         $date_in = $d['DailyCallReport']['datetime_in'];

      }
      else{
          $current_row_date = $d['DailyCallReport']['datetime_in'];

          if(strtotime($current_row_date) - (strtotime($date_in)+3600) >= 3600){
             $date_in = $current_row_date;
             echo '<br/>';
          }
      }?>
     <tr>
        <td><?php echo $key+1?></td>     

        <td >
         <?php 
         $date_in = new DateTime($date_in);
         echo $date_in = $date_in -> format('h:i a');
       ?>
       </td>
      </tr> 
  <?php
  }
  endforeach;
?>

您只需跟踪上次日期时间。因此，当您回显它时，不要用格式覆盖它。然后在每次迭代时做一个日期差异。

<?php $date_in = null; ?>
<?php foreach ($dcr_all as $key=>$d):?>

<?php
if ($date_in && $date_in->diff(new DateTime($d['DailyCallReport']['datetime_in']))->format('%h') >= 1) {
    echo "<tr><td></td><td>Message here</td></tr>";
}
?>

  <tr>
        <td><?php echo $key+1?></td>     

        <td >
          <?php $date_in = $d['DailyCallReport']['datetime_in'];
                 $date_in = new DateTime($date_in);
                 //don't overwrite the $date_in with the format here
                 echo $date_in->format('h:i a');
           ?>
        </td>
  </tr>        

<?php  endforeach;?>

这是一个简单的解决方案。只需用当前脚本替换你的脚本，你就会得到一个空行。

<?php 
$lastRowDateTime = null;
foreach ($dcr_all as $key=>$d):
    $date_in = $d['DailyCallReport']['datetime_in'];
    if (!is_null($lastRowDateTime) && strtotime($date_in) > strtotime($lastRowDateTime)+3600) {
        ?>
        <tr><td>your message goes here</td></tr>
    <?php } ?>

    <tr>
        <td><?php echo $key+1?></td>     

        <td>
            <?php
            $date_in = $d['DailyCallReport']['datetime_in'];
            $date_in = new DateTime($date_in);
            echo $date_in = $date_in -> format('h:i a');
            ?>
        </td>
    </tr>

   <?php
    $lastRowDateTime = $d['DailyCallReport']['datetime_in'];
endforeach;
?>
