PHP 8.3 added typed class constants, deep cloning of readonly properties, and the json_validate() function. A solid quality-of-life release.

Key Changes in PHP 8.3

PHP 8.3 has transitioned into security-only maintenance since December 31, 2025. This means it still receives critical security patches, but no new features, performance improvements, or non-critical bug fixes will be backported. It remains a safe choice for production systems that cannot upgrade immediately, but you should begin planning your migration path.

When you are ready to upgrade, PHP 8.5 is the recommended target. Test your application against 8.5 in a staging environment first, paying attention to any deprecated APIs you may be using.
