PHP DOMDocument, Unicode problems

Question

I have some problem here

$source = "<html><body><h1>&#8220;</h1></body></html>";
$dom = new DOMDocument();
$dom->loadHTML($source);
echo $dom->saveHTML();

Output:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><h1>“</h1></body></html>

Ok, this work correctly. But if I want to extract the nodes like this

$source = "<html><body><h1>&#8220;</h1></body></html>";
$dom = new DOMDocument();
$dom->loadHTML($source);
$h1 = $dom->getElementsByTagName('h1');
echo $dom->saveHTML($h1->item(0));

It output unrecognized text.

<h1>â€œ</h1>

Anyone know how to solve this?

All those DOM functions return UTF-8 encoded strings, better check the manual. There is nothing to solve but just to properly display, e.g. tell your browser by either properly configuring your response headers or using the menu in your browser where you can specify the charset-encoding if you don't know how to tell the browser automatically.

Your code example works for me, output is <h1>“</h1>.

&ldquo;    <ENTITY TYPE="#8220"/>    “    Left double quotation mark

Binary UTF-8 sequence of “ is:

0xE2 (226) 0x80 (128) 0x9C (156)
 |          |           `------ Windows-1252: œ
 |          `--- most Windows 125x encodings: €
 `--- ISO 8859-1, 2, 3, 4, 9, 10, 14, 15, 16: â

So where do you view that output?

Probably inside your browser on windows? If inside your browser, have you tried adding

header('Content-Type: text/html; charset=utf-8');

on top of your script?

This might be a defect with saveHTML and using the $node parameter (not using entities while saveHTML w/o $node does).

you need the second parameter of the domdocument constructor (checkout http://nl.php.net/manual/en/domdocument.construct.php):

$dom = new DOMDocument('1.0', 'utf-8');

the HTML source I used to load already encoded, “ . It output correctly when $dom->saveHTML(), but it output to unknown unicode if I print selected nodes, $dom->saveHTML($nodes);
