How to get specific content with PHP and DOM Document?

I have a url I want to grab. I only want a short piece of content from it. The content in question is in a div that has a ID of sample.

<div id="sample">
   Content
</div>

I can grab the file like so:

$url= file_get_contents('http://www.example.com/');

But how do I select just that sample div.

Any ideas?

Solution

  • I'd recommend using the PHP Simple HTML DOM Parser.

    Then you can do:

    $html = file_get_html('http://www.example.com/');
$html->find('div[#sample]', 0);
