php使用DOMDocument更改div但不更新页面

I'm not sure what I'm doing wrong but I'm getting the right nodeValue for what I want. It's just not updating when the php script is done. Here's the code:

我不确定我做错了什么但是我得到了正确的nodeValue以满足我的需求。它只是在php脚本完成时没有更新。这是代码:

    $dom = new DOMDocument();
    //suppress HTML5 and other errors
    libxml_use_internal_errors(true);
    $dom->loadHTMLFile($pageURL);
    libxml_use_internal_errors(false);
    $xpath = new DOMXPath($dom);
    $divContent = $xpath->query("//*[@id='resultStats']/p")->item(0);
    $newText = new DOMText("100 results");
    var_dump($divContent->nodeValue); //returns old test value "400 results" which is correct
    $divContent->removeChild($divContent->firstChild);
    $divContent->appendChild($newText);
    var_dump($divContent->localName); //"p" because i got it from <p> in resultStats
    var_dump($divContent->textContent); //"100 results"
    var_dump($divContent->nodeValue); //"100 results"

    <div class="container">
    <div class="row">
    <div class="resultStats span3 offset1" id="resultStats">
      <p>400 results found.</p>
    </div>
    </div>
    <div class="row">
     <div class="span12">
         <div class="row">
              <div class="span6 offset1">
                  <?php
                         if (isset($_POST['q'])) {
                        //code from above that is executing every time from tests
                         }
                  ?>
               </div>
               <div class="span5">
                  span5
                  </div>
                  </div>
                  </div>
                  </div>

I'm not sure what I'm doing wrong. If I do dom->save it rewrites everything (even php code) so I don't think that's a good idea.

我不确定我做错了什么。如果我做dom->保存它会重写所有内容(甚至PHP代码),所以我认为这不是一个好主意。

I don't understand why you're using DOMDocument for this. Can't you just do this:

我不明白你为什么要使用DOMDocument。你不能这样做:

<div class="container">
<div class="row">
<div class="resultStats span3 offset1" id="resultStats">

<?php

  // get new result count somehow in $resultCount

  echo '<p>'.$resultCount.' results found</p>';
?>
</div>
</div>
