使用 MVC 时如何在循环中处理 html？

Question

有人可以告诉我如何使用 Zend Framework MVC 做这个基本的事情吗？

我正在循环时间戳数据并以这种方式填充我的表。我不明白如何从这个循环中提取演示文稿 HTML 并将其粘贴在视图中？任何帮助将不胜感激！

<table>
<?php
  $day = date("j");
  $month = date("m");
  $year = date("Y");        
  $currentTimeStamp = strtotime("$year-$month-$day"); 
  $numDays = date("t", $currentTimeStamp); 
  $counter = 0; 

            for($i = 1; $i < $numDays+1; $i++, $counter++) 
            { 
                $timeStamp = strtotime("$year-$month-$i"); 
                if($i == 1) 
                { 
                // Workout when the first day of the month is 
                $firstDay = date("w", $timeStamp); 

                for($j = 0; $j < $firstDay; $j++, $counter++) 
                echo "<td>&nbsp;</td>"; 
                } 

                if($counter % 7 == 0) {
                  echo "</tr><tr>"; 
                }

                    echo "<td>" .$i . "</td>";

            }
?> 
</table>

我想将上面的代码转换成函数，但是 HTML 却让我失望了。

******已编辑****（已添加 mvc 解决方案）

不要用不必要的函数、部分等来扰乱您的代码。为什么要从头开始使用 HTML，当您可以创建数据时，然后< /em> 将其转换为 HTML 表格？这是 MVC 示例（以下代码假设有一个名为“default”的单模块项目，如果该项目是基于模块的，则进行相应修改）：

[清单 1] application/controller/IndexController.php

class IndexController extends Zend_Controller_Action {
   public function indexAction() {
      $this->view->calData = new Default_Model_Calendar('2010-07-17');
   }
}

[清单 2] application/models/Calendar.php

class Default_Model_Calendar {
   /* @var Zend_Date */
   private $_date;
   /* @param Zend_Date|string|int $date */
   public function __construct($date) {
      $this->_date = new Zend_Date($date);
   }
   /* @return Zend_Date */
   public function getTime() {
      return $this->_date;
   }
   public function getData() {
      // normally, fetch data from Db
      // array( day_of_month => event_html, ... )
      return array(
         1 => 'First day of month',
         4 => '<span class="holiday">Independence Day</span>',
         17 => '<img src="path/to/image.png" />'
         //...
      );
   }
}

[lisging 3] application/view/scripts/index/index.phtml

echo $this->calendarTable($this->calData);

[清单 4] application/view /helpers/CalendarTable.php

class Default_View_Helper_CalendarTable extends Zend_View_Helper_Abstract {
   private $_calData;
   public function calendarTable($calData = null) {
      if (null != $calData) {
         $this->_calData = $calData;
      }

      return $this;
   }

   public function toString() {
      $curDate = $this->_calDate->getTime();
      $firstDay = clone $curDate();  // clone a copy to modify it safely
      $firstDay->set(Zend_Date::DAY, 1);

      $firstWeekDay = $firstDay->get(Zend_Date::WEEKDAY);
      $numDays = $curDate->get(Zend_Date::MONTH_DAYS);

      // start with an array of empty items for the first $firstweekDay of the month
      $cal = array_fill(0, $firstweekDay, ' ');
      // fill the rest of the array with the day number of the month using some data if provided
      $calData = $this->_calData->getData();
      for ($i=1; $i<=$numDays; $i++) {
         $dayHtml = '<span class="day-of-month">' . $i . '</span>';
         if (isset($calData[$i])) {
            $dayHtml .= $calData[$i];
         }
         $cal[] = $dayHtml;
     }

     // pad the array with empty items for the remaining days of the month
     //$cal = array_pad($cal, count($cal) + (count($cal) % 7) - 1, ' ');
     $cal = array_pad($cal, 42, ' ');   // OR a calendar has 42 cells in total...

     // split the array in chunks (weeks)
     $calTable = array_chunk($cal, 7);
     // for each chunks, replace them with a string of cells
     foreach ($calTable as & $row) {
        $row = implode('</td><td>', $row);
     }
     // finalize $cal to create actual rows...
     $calTable = implode('</td></tr><tr><td>', $calTable);

     return '<table class="calendar"><tr><td>' . $calTable . '</td></tr></table>';
   }
   public function __toString() {
      return $this->__toString();
   }
}

使用此代码，您甚至可以在调用 array_chunk 之前在 $cal 数组中准确设置您想要的内容。例如，$cal[] = $dayHtml 。 'more';

这也遵循真正的 MVC 作为数据（在 Default_Model_Calendar 中）和视图（在 Default_View_Helper_CalendarTable 中） code>) 完全分离，让您可以自由地将任何其他模型与视图助手一起使用，或者干脆不将任何视图助手与您的模型一起使用！
