foreach循环忽略数组内容

Question

我有一个foreach循环遍历数组，并以HTML表格的形式吐出数据。

基本流程如下

<?php foreach($credits as $credit) : ?> 
    <?php if($credit['credit_type'] == "long") : ?> 
      <?php if($credit['category_title'] != $oldvalue) : ?> 
       <?php echo $oldvalue . " changed to ". $credit['category_title']; ?> 
       <br /><?php echo $count; ?> 
       <table width="100%" cellpadding="0" cellspacing="0" border="0"> 
        <tr> 
         <td><?php echo $credit['category_position']; ?></td> 
         <td><?php echo $credit['category_title']; ?></td> 
         <td><strong>Title</strong></td> 
         <td><strong>Role</strong></td> 
         <td><strong>Director</strong></td> 
        </tr> 

        <tr> 
         <td><?php echo $credit['credit_position']; ?></td> 
         <td><?php echo $credit['credit_heading']; ?></td> 
         <td><?php echo $credit['credit_title']; ?></td> 
         <td><?php echo $credit['credit_role']; ?></td> 
         <td><?php echo $credit['credit_director']; ?></td> 
        </tr> 
       </table> 
       <?php $oldvalue = $credit['category_title']; ?> 
       <?php echo $count++; ?> 
      <?php endif; ?> 
     <?php endif; ?> 
     <?php endforeach; ?> 

我的问题是，在第一个循环授信品种为商业和商业有2项然而循环永远只能打印第一位的，而不是第二一，这是为什么？我该如何解决这个问题？

数组我通过这个样子的循环，

Array 
(
    [0] => Array 
     (
      [credit_id] => 5 
      [credit_heading] => Test Heading 4 
      [credit_title] => Test Title 4 
      [credit_role] => Test Role 4 
      [credit_director] => Test Director 4 
      [credit_type] => long 
      [credit_position] => 1 
      [date_created] => 2012-01-05 11:47:50 
      [candidates_candidate_id] => 54 
      [rel_id] => 
      [credits_candidate_id] => 
      [credits_credit_id] => 
      [category_title] => 
      [category_position] => 
     ) 

    [1] => Array 
     (
      [credit_id] => 2 
      [credit_heading] => Test Heading 2 
      [credit_title] => Test Title 2 
      [credit_role] => Test Role 2 
      [credit_director] => Test Director 2 
      [credit_type] => long 
      [credit_position] => 2 
      [date_created] => 2012-01-04 07:46:15 
      [candidates_candidate_id] => 54 
      [rel_id] => 
      [credits_candidate_id] => 
      [credits_credit_id] => 
      [category_title] => 
      [category_position] => 
     ) 

    [2] => Array 
     (
      [credit_id] => 4 
      [credit_heading] => Test Heading 3 
      [credit_title] => Test Title 3 
      [credit_role] => Test Role 3 
      [credit_director] => Test Director 3 
      [credit_type] => long 
      [credit_position] => 1 
      [date_created] => 2012-01-05 10:52:07 
      [candidates_candidate_id] => 54 
      [rel_id] => 2 
      [credits_candidate_id] => 54 
      [credits_credit_id] => 4 
      [category_title] => Commercial 
      [category_position] => 0 
     ) 

    [3] => Array 
     (
      [credit_id] => 6 
      [credit_heading] => Test Heading 4 
      [credit_title] => Test Title 4 
      [credit_role] => Test Role 4 
      [credit_director] => Test Director 4 
      [credit_type] => long 
      [credit_position] => 1 
      [date_created] => 2012-01-05 11:48:31 
      [candidates_candidate_id] => 54 
      [rel_id] => 3 
      [credits_candidate_id] => 54 
      [credits_credit_id] => 6 
      [category_title] => Commercial 
      [category_position] => 0 
     ) 

    [4] => Array 
     (
      [credit_id] => 1 
      [credit_heading] => Test Heading 1 
      [credit_title] => Test Title 1 
      [credit_role] => Test Role 1 
      [credit_director] => Test Director 1 
      [credit_type] => long 
      [credit_position] => 1 
      [date_created] => 2012-01-04 07:46:15 
      [candidates_candidate_id] => 54 
      [rel_id] => 1 
      [credits_candidate_id] => 54 
      [credits_credit_id] => 1 
      [category_title] => Television 
      [category_position] => 1 
     ) 

) 

，并最终输出看起来像这

<table width="100%" cellpadding="0" cellspacing="0" border="0"> 
       <tr> 
        <td>0</td> 
        <td>Commercial</td> 
        <td><strong>Title</strong></td> 

        <td><strong>Role</strong></td> 
        <td><strong>Director</strong></td> 
       </tr> 

       <tr> 
        <td>1</td> 
        <td>Test Heading 3</td> 

        <td>Test Title 3</td> 
        <td>Test Role 3</td> 
        <td>Test Director 3</td> 
       </tr> 
      </table> 
      <table width="100%" cellpadding="0" cellspacing="0" border="0"> 

       <tr> 
        <td>1</td> 
        <td>Television</td> 
        <td><strong>Title</strong></td> 
        <td><strong>Role</strong></td> 
        <td><strong>Director</strong></td> 

       </tr> 

       <tr> 
        <td>1</td> 
        <td>Test Heading 1</td> 
        <td>Test Title 1</td> 
        <td>Test Role 1</td> 

        <td>Test Director 1</td> 
       </tr> 
      </table> 

Answer 1

你唯一的输出表，如果category_title是不同的：

<?php if($credit['category_title'] != $oldvalue) : ?>

使用以下工作：

<?php foreach($credits as $credit) : ?> 
     <?php if($credit['credit_type'] == "short") : ?> 
      <table width="100%" cellpadding="0" cellspacing="0" border="0"> 
       <tr> 
        <td><?php echo $credit['category_position']; ?></td> 
        <td><?php echo $credit['category_title']; ?></td> 
       </tr> 
       <tr> 
        <td><?php echo $credit['credit_heading']; ?></td> 
        <td><a href="">Edit</a></td> 
       </tr> 
      </table> 
     <?php endif; ?> 
     <?php if($credit['credit_type'] == "long") : ?> 
       <?php if($credit['category_title'] != $oldvalue) : ?> 
        <table width="100%" cellpadding="0" cellspacing="0" border="0"> 
       <?php endif; ?> 
         <tr> 
          <td><?php echo $credit['category_position']; ?></td> 
          <td><?php echo $credit['category_title']; ?></td> 
          <td><strong>Title</strong></td> 
          <td><strong>Role</strong></td> 
          <td><strong>Director</strong></td> 
         </tr> 

         <tr> 
          <td><?php echo $credit['credit_position']; ?></td> 
          <td><?php echo $credit['credit_heading']; ?></td> 
          <td><?php echo $credit['credit_title']; ?></td> 
          <td><?php echo $credit['credit_role']; ?></td> 
          <td><?php echo $credit['credit_director']; ?></td> 
         </tr> 
       <?php $oldvalue = $credit['category_title']; ?> 
       <?php if($credit['category_title'] != $oldvalue) : ?> 
        </table> 
       <?php endif; ?> 

     <?php endif; ?> 
    <?php endforeach; ?> 
    </table> 

Answer 2

的错误是：

<?php if($credit['category_title'] != $oldvalue) : ?> 
// you goes farther only if category changed, so the second etry isn't posting. 

插入后：

<br /><?php echo $count; ?> 

这样的：

<?php endif; ?> 

端到端更换一次ENDIF。
