2 How to Update PHP Version
Now let’s walk through the steps you need to follow to safely update the PHP version of your website.
2.1 Check Your Current PHP Version
Before updating, you should know which PHP version your site is currently running.
To do so, navigate to your WordPress dashboard’s Tools → Site Health page and go to the Info tab, as shown below.
Next, scroll down a little and click to expand the Server tab. This section shows server information, including the PHP version used by your server.
You can also check or change the PHP version directly from your hosting control panel. Most major WordPress hosting providers make this quick and simple.
2.2 Back Up Your Website
I always recommend that you should always back up your site before making big changes, including updating the PHP version of your site.
Even though switching PHP versions usually goes smoothly, having a backup gives you peace of mind. If something doesn’t work as expected, you can restore your site in just a few clicks.
Refer to our dedicated tutorial on backing up the WordPress site.
2.3 Update the WordPress Core, Themes, and Plugins
Before updating PHP, you should make sure everything else on your site is up to date. This includes the WordPress core, themes, and plugins. Doing so keeps your site secure, stable, and ready for the latest web standards.
To do so, navigate to the Updates page from your WordPress dashboard. Here, you can find out if there are any updates available for your website.
To update the plugins, tick the Select All checkbox and click Update Plugins.
Follow the same steps mentioned above to update your WordPress themes.
To update the WordPress version, click the Update to version button, as shown below.
2.4 Update the PHP Version of Your WordPress Site
Now that you’ve backed up your site and updated WordPress, themes, and plugins, it’s time to update your PHP version.
The easiest way to do this is through your hosting control panel. Most top hosting providers make it simple, but the exact steps may look slightly different depending on your host.
For this tutorial, let’s walk through the process in Hostinger.
First, log in to your Hostinger account dashboard. After login, navigate to the Websites tab.
Next, navigate to the Advanced → PHP Configuration menu from the left sidebar, as shown below.
Now, Hostinger will present you with a list of supported and available PHP versions.
Select the PHP version and click the Update button to save your settings.
You’ll receive a confirmation message on your screen. Click on the Confirm button to update the PHP version.
The PHP version will be updated within a few seconds.
Note: If your hosting panel looks different or you can’t find the PHP settings, don’t worry. Most hosting dashboards follow a similar structure, and you can always reach out to your hosting provider’s support team for help.
