How PHP DomDocument Class Will Be Improved in PHP 8.4 to Parse and Serialize Better HTML5 Documents
Until PHP 8.3, PHP developers can use the DOMDocument class to parse HTML pages and files to process them helpfully for their PHP applications.
For instance, the DOMDocument can extract information from sites only available on the web pages.
Unfortunately, the DOMDocument class implementation is based on the LibXML2 library, which is only ready to parse HTML 4 documents.
Therefore, PHP 8.4 will be improved to use a new parser library that can process HTML5 pages and files to parse pages with types of elements only available in HTML5.
Most modern sites use HTML5 to generate their pages to take advantage of new HTML page elements not supported by HTML 4.
PHP 8.4 will be the next official version that PHP core developers will release, with improved features and better security protection.
You can read this short article on this page to see some PHP code, learn how to take advantage of this improvement of PHP 8.4, and know when it will be available for you to use in your PHP applications.
