(PHP 5)
The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.
$namespaceURI
= NULL
[, string $qualifiedName
= NULL
[, DOMDocumentType $doctype
= NULL
]]] )$qualifiedName
= NULL
[, string $publicId
= NULL
[, string $systemId
= NULL
]]] )giorgio dot liscio at email dot it (2010-07-20 18:26:31)
officially, the w3 specifies that the way to access dom interfaces is through this class
so if you use
$doc = new DOMDocument("1.0", "UTF-8");
use instead:
$x = new DOMImplementation();
$doc = $x->createDocument(NULL,"rootElementName");
$doc->xmlVersion="1.0";
$doc->xmlEncoding="UTF-8";
it is not required by php's implementation, but, probably, it is a good practice
