You should always keep the PHP up to date. This is for better security of the websites running on the web host. The update process does not break websites. But it will be an intelligent move to take a backup of the websites before performing this.
If you are on WordPress site, you may see a warning if the site is running on an older PHP version. You can update the PHP version on your GoDaddy cPanel yourself, or you can ask your host provider to update it for you.
I have explained how to update the PHP version on GoDaddy cPanel, follow the guide…
Update the PHP version in GoDaddy cPanel
- On the GoDaddy control panel click on Select PHP version.
- Click on the drop-down list beside Current PHP version. You can see which PHP version is select currently and the latest versions of PHP available. Select the latest one.
- After selecting the latest PHP version, click on Set as current to update it to the latest one. It will take a moment to update.
