What role does PHP version play in WordPress performance?

Your PHP version can directly impact your WordPress site’s performance. If you are using an outdated PHP version, you are risking slowing your site down and exposure to serious security threats. Updating PHP versions to 8.0 or above can make your site faster, safer to bugs and threats. It also makes it more compatible with modern themes and plugins and improves your SEO rankings. You can check your current PHP version in your hosting dashboard. If it is below PHP 8.0, upgrade it to the latest stable version for a better speed, performance and security for your WordPress site.
