如何从PHP中的数据库中检索复选框值？

Question

这是我的代码

<tr><td valign="top">Sebab Kekosongan</td>
      <?php
            $QQQ = "SELECT sbbKekosongan FROM infojawatan WHERE ID = '$ID'";
            $rs_QQQ = mysql_query($QQQ);
            while($row_QQQ = mysql_fetch_array($rs_QQQ))
            {
                $kerana = explode(",", $row_QQQ['kerana']); ?>  
     <td>           
    <input type="checkbox" name="kerana[]" value="retire" <?php if(in_array("retire",$kerana)) echo 'checked="checked"' ?>> Bersara

＆gt; Meninggal Dunia         ##继续编码##      
        ＆GT; Bertukar

    <input type="checkbox" name="kerana[]" value="promote" <?php if(in_array("promote",$kerana)) echo 'checked="checked"' ?>> Naik Pangkat

    <input type="checkbox" name="kerana[]" value="others"  <?php if(in_array("others",$kerana)) echo 'checked="checked"' ?>> Lain -lain

      </td>  <?php } ?>  </tr> 

我的第二个测试代码

 <tr><td valign="top">Sebab Kekosongan</td><td>
        <?php 
            $keranaS = array('retire', 'death', 'change', 'promote', 'others');
            if(! empty($keranaS))
            {
                foreach ($keranaS as $myKerana)
                {
                    $checked = (in_array($myKerana, $kerana)) ? 'checked="checked"' : ''; ?>

                   <input type="checkbox" name="kerana[]" value="<?php echo $myKerana; ?>" <?php echo $checked; ?>> <?php echo $myKerana;?>
          <?php } ?>
          </td>
    <?php   } ?>

    </tr>

我试过了两个。但是它不起作用
