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.
