Strange PHP DOMDocument Warning

Question

This code below gives me a DOMDocument Warning and I wonder why. Is there anything I can do to fix it, or not display this particular warning? I'm running php on windows xp and iis.

$content = "<html><body><p>'HTTP_REFERER' => 'http://localhost/?table=event_occurrence_person&LB1ID='</p></body></html>";
$dom = new DOMDocument;
$dom->loadHTML($content);

Warning: DOMDocument::loadHTML(): htmlParseEntityRef: expecting ';' in Entity, line: 1 in...

Answer 1

There's a bare & in the HTML. & signals the start of an HTML entity, a bare & needs to be represented as the entity & . That's where the warning comes from.

You can silence warnings using @ :

@$dom->loadHTML($content);

If you have full control over the HTML, you should not silence warnings. If you are parsing other people's HTML, you may have no choice.

Answer 2

Well, your XML is malformed.

=> must be escaped to => (optional, not blocking)
&LB1ID must be escaped to &LB1ID (raises your warning)
