问题描述

我有一个上班时间的数据库，我需要将它们以某种格式导出到pdf（我可以这样做）。 记录具有单个日期，带有打入和打出时间（以及需要结转的其他数据）： 

Date     Punch IN     Punch OUT

我需要格式化要导出的数据，以便具有多次打入和打入的任何日期都始终在同一行/记录上。 所以我可以像在pdf中那样导出它： 

Date     Punch IN(1)   Punch OUT(1)   Punch IN(2)   Punch OUT(2) (ETC)

我的问题是我使用下面的代码浏览包含所有记录的初始数组，并且导出几乎是正确的，但是由于某种原因，第一个记录被最后一个记录覆盖。 因此，我总是会丢失第一张唱片，显然我需要修正它，但是对于我一生来说，我做不到。

下面的代码创建了新数组，因此我可以将其导出到pdf中（我知道该怎么做）。 

$punchpdfexport = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'Total'=> '', 'NotesIN' => '', 'NotesOut' => '']);
  $punchpdfexportprev = null;

  $pdfexportpunch = array();

  $previousrow = '';
  $previouscount = 0;
  $count = 0;
  $length = count($punch);
  $check = 0;

  foreach ($punch as $row){
    if ($previousrow != '' && $previousrow->PunchINDate == $row->PunchINDate){
      $count += 1;
      if(($punchpdfexportprev[0]->IN != '') && $count == 1){
        $punchpdfexporttwo = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'Total'=> '', 'NotesIN' => '', 'NotesOut' => '']);
        $punchpdfexporttwo[0]->Date = $punchpdfexportprev[0]->Date;
        $punchpdfexporttwo[0]->IN = $punchpdfexportprev[0]->IN;
        $punchpdfexporttwo[0]->OUT = $punchpdfexportprev[0]->OUT;
        $punchpdfexporttwo[0]->IN_2 = $row->PunchInTime;
        $punchpdfexporttwo[0]->OUT_2 = $row->PunchOutTime;
        $result = $this->functions->secondssum($row->TotalTime,$punchpdfexportprev[0]->Total);
        $punchpdfexporttwo[0]->Total = $result.":00";
        $punchpdfexporttwo[0]->NotesIN = $punchpdfexportprev[0]->NotesIN . $row->NotesIN;
        $punchpdfexporttwo[0]->NotesOut = $punchpdfexportprev[0]->NotesOut . $row->NotesOut;
        if ($check == $length - 1){
          $pdfexportpunch[$punchpdfexporttwo[0]->Date] = $punchpdfexporttwo;
          break;
        }
      }elseif (($punchpdfexportprev[0]->IN != '') && $count == 2){
        $punchpdfexportthree = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'IN_3' => '', 'OUT_3' => '', 'Total' => '', 'NotesIN' => '', 'NotesOut' => '']);

        $punchpdfexportthree[0]->OUT_2 = $punchpdfexporttwo[0]->OUT_2;
        $punchpdfexportthree[0]->IN_3 = $row->PunchInTime;
        $punchpdfexportthree[0]->OUT_3 = $row->PunchOutTime;
        $result = $this->functions->secondssum($row->TotalTime,$punchpdfexporttwo[0]->Total);

    }else{

    }
    $previousrow = $row;
    $punchpdfexportprev = $punchpdfexport;
    $check++;
  }
  var_dump($pdfexportpunch);

我在末尾使用var_dump来查看foreach循环的结果，如下所示： 

 array (size=4)
  '2018-08-22' => 
array (size=1)
  0 => 
    object(stdClass)[50]
      public 'Date' => string '2018-08-30' (length=10)

      public 'NotesIN' => string 'hfgftesting again' (length=17)
      public 'NotesOut' => string 'testdgtesting later' (length=19)
  '2018-08-30' => 
array (size=1)
  0 => 
    object(stdClass)[56]
      public 'Date' => string '2018-08-30' (length=10)
      public 'IN' => string '08:49:52' (length=8)
      public 'OUT' => string '09:29:01' (length=8)
      public 'IN_2' => string '09:32:16' (length=8)
      public 'OUT_2' => string '11:21:19' (length=8)
      public 'IN_3' => string '11:21:22' (length=8)
      public 'OUT_3' => string '12:24:36' (length=8)
      public 'IN_4' => string '13:52:47' (length=8)
      public 'OUT_4' => string '15:08:54' (length=8)
      public 'IN_5' => string '12:59:10' (length=8)

      public 'NotesIN' => string 'testing 1 2 3hello there' (length=24)
      public 'NotesOut' => string '' (length=0)

那里的第一条记录应该与它的关键2018-08-22相同，但是相反，它被最后一个2018-08-30所覆盖，我不知道为什么，除非它是内置函数问题。 否则，其他3条记录是完美的，并且可以按预期工作。

如您所见，我尝试使用日期作为键将新的数组对象插入到数组中，这样就不会发生覆盖问题。

我希望这只是一个简单的重写，以便能够工作，如果有更好的解决方法，请让我知道我想像有，但是在使用array_push，array_merge，array_merge_recursive之类的方法搜索之后，给出了同样的问题或更糟。

而不是一劳永逸地构建，这会导致混乱 

'2018-08-30' => 
array (size=1)
  0 => 
    object(stdClass)[56]
      public 'Date' => string '2018-08-30' (length=10)
      public 'IN' => string '08:49:52' (length=8)
      public 'OUT' => string '09:29:01' (length=8)
      public 'IN_2' => string '09:32:16' (length=8)
      public 'OUT_2' => string '11:21:19' (length=8)
      public 'IN_3' => string '11:21:22' (length=8)
      public 'OUT_3' => string '12:24:36' (length=8)
      public 'IN_4' => string '13:52:47' (length=8)
      public 'OUT_4' => string '15:08:54' (length=8)
      public 'IN_5' => string '12:59:10' (length=8)
      public 'OUT_5' => string '13:52:19' (length=8)
      public 'Total' => string '05:45:00' (length=8)
      public 'NotesIN' => string 'testing 1 2 3hello there' (length=24)
      public 'NotesOut' => string '' (length=0)

将数据分组为以下结构： 

    [ 
       '2018-08-30' => [
          'Date' => '2018-08-30',
          'Punches' => [ 
            ['IN' => '08:49:52', 'OUT' => '09:29:01'],
            ['IN' => '09:32:16', 'OUT' => '11:21:19'],
            ['IN' => '11:21:22', 'OUT' => '12:24:36']
          ],
          'Total' => '05:45:00'
          'NotesIN' => 'testing 1 2 3hello there'
          'NotesOut' => ''
       ],
     ....
     ]

然后重新处理并构建您的对象。 这样做会容易得多 

  foreach($Punches as $key=>$punch){
      $postfix = empty($key) ? "" : "_$key";

       $obj->{"IN{$postfix}"} = $punch["IN"];
       $obj->{"OUT{$postfix}"} = $punch["OUT"]; 
 }

要将它们添加到对象中，这还应允许您删除所有重复的代码，例如查看以下内容： 

if(($punchpdfexportprev[0]->IN != '') && $count == 1){
    $punchpdfexporttwo = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'Total'=> '', 'NotesIN' => '', 'NotesOut' => '']);
    $punchpdfexporttwo[0]->Date = $punchpdfexportprev[0]->Date;
    ...
}elseif (($punchpdfexportprev[0]->IN != '') && $count == 2){
    $punchpdfexportthree = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'IN_3' => '', 'OUT_3' => '', 'Total' => '', 'NotesIN' => '', 'NotesOut' => '']);
    $punchpdfexportthree[0]->Date = $punchpdfexporttwo[0]->Date;   
    ...  
}elseif (($punchpdfexportprev[0]->IN != '') && $count == 3){
    $punchpdfexportfour = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'IN_3' => '', 'OUT_3' => '', 'IN_4' => '', 'OUT_4' => '', 'Total'=> '', 'NotesIN' => '', 'NotesOut' => '']);
    $punchpdfexportfour[0]->Date = $punchpdfexportthree[0]->Date;
    ...
}elseif (($punchpdfexportprev[0]->IN != '') && $count == 4){
    $punchpdfexportfive = array((object)['Date' => '', 'IN' => '', 'OUT' => '', 'IN_2' => '', 'OUT_2' => '', 'IN_3' => '', 'OUT_3' => '', 'IN_4' => '', 'OUT_4' => '', 'IN_5' => '', 'OUT_5' => '', 'Total' => '', 'NotesIN' => '', 'NotesOut' => '']);
    $punchpdfexportfive[0]->Date = $punchpdfexportfour[0]->Date;
    ....
}else{

除了要放入变量的名称外，所有这些都重复了。对于我来说，要想出一个完整的解决方案而又没有原始数据集可以使用，对我来说太过分了。

但希望有帮助。

我知道，请相信我我也不喜欢它，但是我打算在工作后对其进行简化。

很好，但这就是注释的目的，只需注释掉旧代码，然后从新代码开始。 问题在于，从根本上来说这是有缺陷的，因为您所需的结构不存在。 因此，要修复此问题，您将可以用任何方式对其进行重写。

复制或WET（两次写入所有内容）是一个杀手，因为它不可能维护具有重复的代码。 如果您想在其中添加一个字段，则必须对其进行编辑并将其添加到所有重复的内容中，如果您错过了某个字段，您可能不会意识到某些错误的正确方法，因此必须遍历所有寻找您错过了某个内容的位置。

尝试编写DRY（请勿重复自己）代码。 每当我发现自己一遍又一遍地编写相同的代码时，我都会重新考虑它的结构，因为那是您代码的基础。 固定地下室正在坍塌的房屋毫无意义。

UPDATE

对于第一部分，您想要做这样的事情（我不知道您的数据是什么样的，所以我只介绍它） 

     $data = [];
     foreach ($punch as $row){
        $key = $row['date'];
        if(!isset($data[$key])){
           $data[$key] = [
              'Date' => $row['date'],
              'Punches' => [],
              'Total' => 0
              'NotesIN' => ''
              'NotesOut' => ''
           ];
        }

        $data[$key]['Punches'][] = [
            'IN' => $row['IN']
            'OUT' => $row['OUT']
        ];
        $data[$key]['Total'] += $row['Total'];
        $data[$key]['NotesIN'] .= ' '.$row['NotesIN'];
        $data[$key]['NotesOUT'] .= ' '.$row['NotesOUT'];
     }

然后，在$data上循环并从中创建对象。 您可以将代码减少约80％。 更少的代码，更少的错误，更少的可修复问题，等等。

如果可以使代码更具可读性，那么遍历相同的数据两次就没有错。 即使没有这样做，我也看到了将示例组合成一个示例的方法。 但是可读性是我书中的第一位。 没有它，您将永远找不到错误或无法修复它们，因为您无法阅读代码。

我要说的最后一件事是问自己第六次打孔发生了什么，您只编写了句柄5。我展示的示例可以处理任意数量的打孔。 我的猜测是，这会将$counter重置$counter 0并覆盖内容。

干杯!
