// мы хотим красивый вывод
$doc->formatOutput = true;

$root = $doc->createElement('html');

saveHTMLFile() always saves the file in UTF-8. Even if the DOMDocument->encoding explicitly prescribe different from UTF-8 encoding. All "non-Latin" characters will be converted to HTML-entities. Tested in PHP 5.2.9-2 and PHP 5.2.17. Example:

=new domDocument('1.0', 'WINDOWS-1251');
$document->loadHTML('<html><head><title>Russian language</title></head><body>Русский язык</body></html>');
"Записано байт. Recorded bytes: ".$document->saveHTMLFile('html.html');

Method recorded file in UTF-8 encoding. The contents of the file html.html:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Russian language</title>
<body>Ðóññêèé ÿçûê</body>

Not mentioned in the documentation is the fact that using DOMDocument::saveHTMLFile() will automatically overwrite the contents if an existing file is used - with no notice, warning or error thrown.

Make sure you check the filename before using this function so that you don't accidentally overwrite important files.


= fopen('test.html', 'w');
fwrite($file, 'this is some text');

$doc = new DOMDocument();
$doc->formatOutput = true;

// test.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">


If you're dynamically generating a series of pages using DOMDocument objects, make sure you are also dynamically generating the file or directory names using something that can't easily be confused for an existing file/folder, or check if the desired path already exists before saving so that you don't accidentally delete previous files.

I foolishly assumed that this function was equivalent to
($filename, $document->saveHTML());
but there are differences in the generated HTML:
= new DOMDocument();
$doc->encoding = 'iso-8859-1';

#<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "">

#<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "">
#<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Test</title></head><body></body></html>

Note that saveHTMLFile() adds a UTF-8 meta tag despite the ISO-8859-1 document encoding.
