The DOMImplementation class

(PHP 5)

Introduction

The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.

Class synopsis

DOMImplementation {

/* Properties */

/* Methods */

__construct ( void )

DOMDocument createDocument ([ string $namespaceURI = NULL [, string $qualifiedName = NULL [, DOMDocumentType $doctype = NULL ]]] )

DOMDocumentType createDocumentType ([ string $qualifiedName = NULL [, string $publicId = NULL [, string $systemId = NULL ]]] )

bool hasFeature ( string $feature , string $version )

}

DOMImplementation::__construct — Creates a new DOMImplementation object
DOMImplementation::createDocument — Creates a DOMDocument object of the specified type with its document element
DOMImplementation::createDocumentType — Creates an empty DOMDocumentType object
DOMImplementation::hasFeature — Test if the DOM implementation implements a specific feature

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 



see:
