WordPress continues to be used on a wide range of PHP and MySQL versions. While the recommended versions are PHP 5.2.4 and MySQL 5.0, WordPress is commonly used on PHP 5.3-5.5 and MySQL 5.1-5.6. Older versions of PHP and MySQL also maintain significant usage rates. This flexibility allows WordPress to run on a wide variety of server environments.
