字符串 按特征码截取

Question

<tr>
  <th valign="top">文章内容</th>
  <td>
    <textarea class="required" cols="40" id="topic_body" name="topic[body]" rows="20">
</textarea>
    <div class="body_count">
      <span id="topic_body_count_notice">你还可以输入10000个字符</span>
    </div>
  </td>
</tr>
<tr>
  <th>标签</th>
  <td>
    <input id="topic_cached_tag_list" name="topic[cached_tag_list]" type="hidden" />
    <div id="tags"></div>
    <span class="red">最多添加5个标签，多个标签之间用","(英文逗号)分隔</span>
  </td>
</tr>例如上面字符串 特征码如果是 <tr> </tr> 需要把 每个 <tr> 内容写入数组 并输出 ，变化特征码 为 <th> 时 ，输出数组中为 th 内容 

Answer 1

preg_match_all 不会用，貌似需要用这个来解决。。

Answer 2

function ($str,'<tr>','</tr>'){
....
}输出 数组 ，数组内容 是 tr里面的内容。

Answer 3

preg_match_all('/<tr>(.+)<\/tr>/isU',$s,$m);
print_r($m[1]);

Answer 4

追问一下 preg_match_all 哪里有这个详解啊问题基本解决了，谢谢，给分
