You can use the DOMDocument class in PHP. 

Documentation: 
<a href="http://php.net/manual/en/class.domdocument.php" rel="nofollow">http://php.net/manual/en/class.domdocument.php</a>

Example: 

<pre><code>$documentText = file_get_contents("http://site.com/document.html");
$domDocument = new DOMDocument();
$domDocument-&gt;loadHTML( $documentText );
$myDivNode = $domDocument-&gt;getElementById( 'the-id-of-the-div' );
$myDivText = $domDocument-&gt;saveHTML( $myDivNode );
echo $myDivText;
</code></pre>

You have two ways to do it:

<ol>
<li>If the remote site has CORS headers (Access-Control-Allow-Origin: *), you can inject it using an AJAX request; Please note that this will fail on browsers that do not support CORS</li>
<li>You can parse it on the server</li>
</ol>

Option 2 is by far your preferred approach and relies on two libraries (three if you're like me): curl, which will handle the HTTP request, and DOMDocument, which handles the parsing.

I wrote a parser for someone a while back. You can find it there: <a href="https://stackoverflow.com/a/16144603/2167834">https://stackoverflow.com/a/16144603/2167834</a> . It has a lot of detailed explanations on how to go through the DOM using <code>DOMDocument</code>.

Please note that <code>DOMDocument</code> is especially prone to breaking on the following:

<ol>
<li>Incorrect charset definitions</li>
<li>Broken HTML</li>
<li>Inline JavaScript</li>
</ol>

You can, however, rewrite your source to deal with this.

In your case, once you have the DOMDocument and DOMXPath object, you want to <code>query("//[@id=\"cmform\"]")</code>. The two forward slashes mean "any parent", [@id is an exact match on the parameter id.

Note that **this will fail if the DOM document has multiple elements with the same ID. They shouldn't have, by HTML spec.

blocks|key|5055513|text|实际上，file_get_contents()返回一个代表文件内容的字符串，最简单的方法是解析该字符串以获得div的值，请查看此示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5055514|$html+=+'hola+<div+id="cmform">'.
++++++++++++"the+content+of+div".

Actually <a href="http://php.net/manual/en/function.file-get-contents.php" rel="nofollow">file_get_contents()</a> returns an string representig the content of the file, the simplest way you have is to parse the string to get the value of the div, check this example: 

<pre><code>$html = 'hola &lt;div id="cmform"&gt;'.
 "the content of div".
 "&lt;/div&gt;adios";

echo preg_replace('/(.+)&lt;div id="cmform"&gt;(.+)&lt;\/div&gt;(.+)/m', '\2', $html);
</code></pre>

I want to include a section of one html document (X) in another one (Y).

There's:

<pre><code>&lt;div id="cmform"&gt;
....
....
&lt;/div&gt;
</code></pre>

in html document X and I need to include it in a div in html document Y. I started to read PHP documentation and have found an info about "file_get_contents" function. If I do:

<pre><code>&lt;?php
 $a = file_get_contents("http://site.com/document.html");
 echo ($a);
?&gt;
</code></pre>

I get the whole page and I don't know how to... narrow it to that one div...
