The DOMImplementation class

(PHP 5, PHP 7, PHP 8)

Introduction

This class provides a number of methods for performing operations that are independent of any particular instance of the document object model.

class DOMImplementation {

/* Methods */

public function createDocument(?string $namespace = null, string $qualifiedName = "", ?DOMDocumentType $doctype = null): DOMDocument

public function createDocumentType(string $qualifiedName, string $publicId = "", string $systemId = ""): DOMDocumentType|false

public function hasFeature(string $feature, string $version): bool

}

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
