WordPress has announced that they will discontinue support for PHP 5 in the upcoming WordPress version 6.3, set to release on August 8, 2023. This decision implies that the new minimum supported PHP version for WordPress will be PHP 7.0. Users are thus advised to upgrade their sites to at least PHP 7.0 to avoid potential issues and vulnerabilities.
PHP 5 reached its end of life on January 1, 2019. This means there are no further updates or security fixes for this version after this date, making it potentially insecure and vulnerable. It’s highly recommended to upgrade to a supported version of PHP to ensure the security and functionality of your applications.
