Fortunately, updating your PHP version is a relatively painless process, and this guide will help you through it. Let’s start by sharing the reasons why you should update the PHP version in the first place.

Why Update the PHP Version of Your WordPress Site?

WordPress is a CMS platform powered by a programming language called PHP. Thus, a big part of the security and speed of your WordPress site depends on the version of PHP you are using to power your site.

A newer PHP version comes with more stability, efficiency and of course fewer vulnerability issues. This helps your site to become faster and more secure.

Right now, WordPress requires that you use PHP 7.4 at least on your website, while the latest version is 8.1.1. Because of the requirement set by WordPress, most hosting providers now use at least 7.4 or newer.

Moreover, many WordPress plugins also depend on having a newer version of PHP. These plugins may not work properly if you don’t update the PHP version of your website.

Now you know why it is very important to update the PHP version of your website.

How to Check PHP Version of Your WordPress Site?

There are two different ways to know which PHP version you are using on your website. You can either know it from the WordPress admin dashboard, or from the hosting panel (cPanel/any other backend panel that your hosting uses).

The easiest way is obviously using the admin dashboard, as you won’t have to log in to your hosting backend panel.

  • To check PHP Version in this way, first, navigate to WordPress Admin Dashboard > Tools > Site Health.
Check PHP version
  • Now click on the Info tab and you will find the PHP Version under the Server option.

  • First, log in to Namecheap or any hosting you might be using. Now navigate to Account > Dashboard > Hosting List. (You can find almost similar options from other hosting providers as well.)
  • Now click on Go to cPanel button of the domain, of which you want to update the PHP version.
Access your cPanel
  • Now you should be inside the cPanel of your domain. Scroll down, and you will find an option called Select PHP Version. Click on IT.
