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:

<?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(); ?> |
