The DOMDocumentType class

(PHP 5, PHP 7, PHP 8)

Introduction

Each DOMDocument has a doctype attribute whose value is either null or a DOMDocumentType object.

Properties

publicId

The public identifier of the external subset.

systemId

The system identifier of the external subset. This may be an absolute URI or not.

name

The name of DTD; i.e., the name immediately following the DOCTYPE keyword.

entities

A DOMNamedNodeMap containing the general entities, both external and internal, declared in the DTD.

notations

A DOMNamedNodeMap containing the notations declared in the DTD.

internalSubset

The internal subset as a string, or null if there is none. This does not contain the delimiting square brackets.
