How Can I Efficiently Retrieve the Outer HTML of a DOM Node in PHP?

Returning Outer HTML of DOMDocument

Retrieving the complete HTML code for specific elements like hyperlinks can be challenging when using DOMDocument's outerHTML property. However, there are alternative approaches available.

Prior to PHP 5.3.6, the DOMDocument class lacked the functionality to directly output the outer HTML of a node. Instead, using saveXml() was the preferred method. While it generated XML-compliant markup, this posed no significant issue for elements like tags.

With the introduction of PHP 5.3.6, the saveHtml() method was introduced, which allowed you to provide a node as an argument and retrieve its outer HTML. The code below demonstrates this approach:

$domDocument->saveHtml($nodeToGetTheOuterHtmlFrom);

By leveraging this method, you can efficiently retrieve the outer HTML code for any DOM node, including hyperlinks.
