I foolishly assumed that this function was equivalent to <?php file_put_contents($filename, $document->saveHTML()); ?> but there are differences in the generated HTML: <?php $doc = new DOMDocument(); $doc->loadHTML( '<html><head><title>Test</title></head><body></body></html>' ); $doc->encoding = 'iso-8859-1'; echo $doc->saveHTML(); #<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> #<html> #<head><title>Test</title></head> #<body></body> #</html> $doc->saveHTMLFile('output.html'); #<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> #<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.
