A Guide to Updating Your PHP Version in WordPress - ManageWP

If you use WordPress, you’re also using PHP. As the underlying programming language for this Content Management System (CMS), PHP affects everything from your site’s security to its performance. Therefore, it’s vital to make sure you’re using an updated version.

Fortunately, upgrading to the newest PHP version in WordPress is a quick and simple process. Once you determine which release you’re currently using, you can take the necessary steps to update it if needed.

In this post, we’ll explain why it’s important to use the latest version of PHP on your WordPress site. Then we’ll walk you through how to check your current version, as well as how to update it via cPanel and on other hosting providers. Let’s jump right in!

The importance of using an updated PHP version

WordPress runs on PHP. Therefore, what version you’re using can affect many different aspects of your site, from speed to security. This is just as important for your website’s overall health as keeping your WordPress Core, plugins, and themes up to date.

Currently, WordPress requires you to run at least PHP 7.4. However, the most recent major, stable update available is 8.0. Each PHP version brings performance improvements, bug fixes, and security patches that are designed to make it more efficient and secure.

Many WordPress hosts automatically update PHP for the sites on their servers. This means you could be running the latest version and not even know it. However, it’s best not to assume that’s the case. Instead, we recommend checking to confirm which version you’re currently using, and then upgrading to a more recent version if needed.

Keep in mind that, occasionally, the newest version of PHP may cause a conflict or compatibility issue on your site. For example, a plugin might stop working if its developer hasn’t updated it to work with the latest PHP release.

If this happens, you can either find an alternative plugin or roll back your site to a previous version. For that reason, we highly recommend creating a backup of your site before making any changes to it.
