Dom LoadHTML Problem in PHP

Question

Hi. Maybe I am missing something... but the DOM Object is empty in this code:

$input = file_get_contents('http://www.google.com/');
$doc = new DOMDocument();
@$doc->loadHTML($input); //supress errors on invalid html!
var_dump($doc);
die();

I really don't know what could be wrong with that code. I have verified that $input is actually filled with the html contents of the web page.

The output is: object(DOMDocument)#3 (0) { }

I don't understand why...

Answer 1

If we remove @, then warnings from loadHTML due to invalid syntax of the html document to load . It may be because of few html tags causing problems.

try to replace

$doc->loadHTML($input);

with

$doc->loadHTML(htmlentities($input));

Hope this helps.

Answer 2

This is expected behaviour. To see the HTML, use DOMDocument::saveHTML() (or saveXML()).

Answer 3

The output is: object(DOMDocument)#3 (0) { }

Yes. That's what a var_dumped DOMDocument looks like.

If you want to look at the HTML representation of the content inside the document, saveHTML() on it. That spits out a cleaned up version of the HTML on Google's home page for me.
