(No version information available, might be only in CVS)
DOMDocument::loadHTML — Charge du HTML à partir d'une chaîne de caractères
Description
Cette fonction analyse un document HTML contenu dans la chaîne source . Contrairement au XML, le HTML n'a pas besoin d'être bien formé pour être chargé. Cette fonction peut aussi être appelée statiquement pour charger et créer un objet DOMDocument. L'appel statique peut être utilisé lorsque vous n'avez besoin de configurer aucune propriété de DOMDocument avant le chargement.
Liste de paramètres
- source
-
La chaîne HTML.
Valeurs de retour
Cette fonction retourne TRUE en cas de succès, FALSE en cas d'échec.
Erreurs / Exceptions
Si une chaîne vide est passée comme paramètre source , une alerte sera générée. Cette alerte n'est pas générée par libxml, et ne peut être gérée en utilisant les fonctions de gestion d'erreur de libxml.
Exemples
Exemple #1 Création d'un document
<?php
$doc = new DOMDocument();
$doc->loadHTML("<html><body>Test<br></body></html>");
echo $doc->saveHTML();
?>

If you use loadHTML() to process utf HTML string (eg in Vietnamese), you may experience result in garbage text, while some files were OK. Even your HTML already have meta charset like
<meta http-equiv="content-type" content="text/html; charset=utf-8">
I have discovered that, to help loadHTML() process utf file correctly, the meta tag should come first, before any utf string appear. For example, this HTML file
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title> Vietnamese - Tiếng Việt</title>
</head>
<body></body>
</html>
will be OK with loadHTML() when <meta> tag appear <title> tag.
But the file below will not regcornize by loadHTML() because <title> tag contains utf string appear before <meta> tag.
<html>
<head>
<title> Vietnamese - Tiếng Việt</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
</head>
<body></body>
</html>

The comment from bigtree at DONTSPAM dot 29a dot nl

In addition I noted that if your doctype declaration is not valid, DomDocument::loadHtml won't respect your charset=utf-8. It made me crazy. Beware!

When using loadHTML() to process UTF-8 pages, you may meet the problem that the output of dom functions are not like the input. For example, if you want to get "Cạnh tranh", you will receive "Cạnh tranh". I suggest we use mb_convert_encoding before load UTF-8 page :
<?php
$pageDom = new DomDocument();
$searchPage = mb_convert_encoding($htmlUTF8Page, 'HTML-ENTITIES', "UTF-8");
@$pageDom->loadHTML($htmlUTF8Page);
?>

Note that the elements of such document will have no namespace even with <html xmlns="http://www.w3.org/1999/xhtml">

Pay attention when loading html that has a different charset than iso-8859-1. Since this method does not actively try to figure out what the html you are trying to load is encoded in (like most browsers do), you have to specify it in the html head. If, for instance, your html is in utf-8, make sure you have a meta tag in the html's head section:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
If you do not specify the charset like this, all high-ascii bytes will be html-encoded. It is not enough to set the dom document you are loading the html in to UTF-8.
