The PHP version installed on the web server affects the speed of WordPress. If you’re running an older version of PHP, upgrading to the latest version can improve speed. For example, upgrading from PHP 5.6 to 7.0 can decrease WordPress load times by up to 50%. In addition, using an object-caching system like APC or Memcached can further improve performance. Object caching stores objects in memory so they can be retrieved quickly, reducing the number of times WordPress has to query the database. If you’re looking to speed up your WordPress site, upgrading to the latest version of PHP and installing an object-caching system are two good places to start.

2. Improved Security

WordPress is a tempting target for hackers, as there are always new vulnerabilities to exploit. That’s why it’s important to keep your WordPress installation up to date, including the PHP version that it runs on. Older versions of PHP are no longer supported by the WordPress team, which means they may contain security vulnerabilities that have not been patched. By running the latest version of PHP, you can help to keep your WordPress site secure against potential attacks.

3. Compatibility

Certain WordPress versions have to be compatible with the PHP version running in your hosting server. That’s why compatibility is the most important to check before installing or using a certain PHP version.
