The DOMImplementation::createDocument() function is an inbuilt function in PHP which is used to create a DOMDocument object of the specified type with its document element.
Syntax:
DOMDocument DOMImplementation::createDocument( string $namespaceURI = NULL, string $qualifiedName = NULL, DOMDocumentType $doctype = NULL )
Parameters: This function accepts three parameters as mentioned above and described below:
- $namespaceURI (Optional): It specifies the namespace URI of the document element to create.
- $qualifiedName (Optional): It specifies the qualified name of the document element to create.
- $doctype (Optional): It specifies the type of document to create or NULL.
Return Value: This function returns DOMDocument object on success.

Below examples illustrate the DOMImplementation::createDocument() function in PHP:
Example 1:
<?php // Create a DOMImplementation instance $documentImplementation = new DOMImplementation(); // Create a document $document = $documentImplementation ->createDocument(null, 'html' ); // Get the document element $html = $document ->documentElement; // Create a HTML element $head = $document ->createElement( 'html' ); // Create a strong element $title = $document ->createElement( 'strong' ); $text = $document ->createTextNode( 'neveropen' ); $body = $document ->createElement( 'body' ); // Append the children $title ->appendChild( $text ); $head ->appendChild( $title ); $html ->appendChild( $head ); $html ->appendChild( $body ); // Render the XML echo $document ->saveXML(); ?> |
Output:
Example 2:
<?php // Create a DOMImplementation instance $documentImplementation = new DOMImplementation(); // Create a document $document = $documentImplementation ->createDocument(null, 'html' ); // Get the document element $html = $document ->documentElement; // Create a HTML element $head = $document ->createElement( 'html' ); // Create a paragraph element $p = $document ->createElement( 'p' ); // Create a text node $text = $document ->createTextNode( 'neveropen' ); // Append the children $p ->appendChild( $text ); // Set the CSS using attribute $p ->setAttribute( 'style' , 'color:blue;font-size:100px' ); // Append paragraph to the head of document $head ->appendChild( $p ); // Append head to the html $html ->appendChild( $head ); // Render the XML echo $document ->saveXML(); ?> |
