**The current netcup products contain the latest version of the popular programming language for web applications: PHP 8.3 is now available. This update brings various improvements and bug fixes that further optimize the performance and functionality of PHP.**

One of the innovations concerns dynamic access to class constants. Thanks to this feature, developers access constants in classes in a dynamic way. This opens up new possibilities for the flexibility and expandability of the applications. PHP 8.3 also introduced a new attribute called #[\Override]. It allows checking methods in parent classes.

Another highlight of the update to the PHP programming language is the introduction of the “json_validate” function for JSON validation. In addition, the PHP update was used to make improvements to the “zip” extension.
