Consider this example, test.php
:
<?php
$mystr = "<p>Hello, με काचं ça øy jeść</p>";
var_dump($mystr);
$domdoc = new DOMDocument('1.0', 'utf-8'); //DOMDocument();
$domdoc->loadHTML($mystr); // already here corrupt UTF-8?
var_dump($domdoc);
?>
If I run this with PHP 5.5.9 (cli), I get in terminal:
$ php test.php
string(50) "<p>Hello, με काचं ça øy jeść</p>"
object(DOMDocument)#1 (34) {
["doctype"]=>
string(22) "(object value omitted)"
...
["actualEncoding"]=>
NULL
["encoding"]=>
NULL
["xmlEncoding"]=>
NULL
...
["textContent"]=>
string(70) "Hello, με à¤à¤¾à¤à¤ ça øy jeÅÄ"
}
Clearly, the original string is correct as UTF-8, but the textContent
of the DOMDocument is incorrectly encoded.
So, how can I get the content as correct UTF-8 in the DOMDocument?
The DOM extension was built on libxml2 whose HTML parser was made for HTML 4 - the default encoding for which is ISO-8859-1. Unless it encounters an appropriate meta tag or XML declaration stating otherwise
loadHTML()
will assume the content is ISO-8859-1.Specifying the encoding when creating the DOMDocument as you have does not influence what the parser does - loading HTML (or XML) replaces both the xml version and encoding that you gave its constructor.
Workarounds:
First use
mb_convert_encoding()
to translate anything above the ASCII range into its html entity equivalent.Or hack in a meta tag or xml declaration specifying UTF-8.
Just wanted to post the OP code with the fixes that work for me:
This outputs:
... which is all good now
