To install WordPress, the WordPress PHP and server requirements that you need to consider:
PHP version 7.4 or greater.
MySQL version 8.0 or greater OR MariaDB version 10.1 or greater.
HTTPS support
We recommend that you should use WPEngine hosting to keep your server secure and fast, which is well constructed, easy to use, and help your website be as secure as possible.
NoticeIf you are in a legacy environment where you only have older PHP or MySQL versions, WordPress also works with PHP 5.6.20+ and MySQL 5.0+, but these versions have reached the official End Of Life and as such may expose your site to security vulnerabilities.
