Managing a WordPress site? Make sure you review what version of PHP your site is running on.

As of December 2019, around 62.2% of WordPress sites are running on outdated, prior to 7.2 version of PHP. These sites are vulnerable to hacking.

The safest PHP version that you should be using is the current revision, 7.4, or version 7.3.

So what exactly is PHP? “Hypertext Preprocessor is a server-side scripting language designed for Web development that is also used as a general-purpose programming language.” Simply put, a lot of sites are built on PHP programming language. All WordPress sites in particular.

The primary reason why you need to update your PHP is that the versions prior to 7.3 are no longer receiving security patches, so your site becomes extremely vulnerable to hacking.

Final Takeaway – Considering the fact that only 37.7% of websites are on PHP version 7.3 or higher, the chances of you having to deal with this issue are greater, at least on one of the sites that you manage.

When you log in to your WordPress dashboard, you will see a warning message which is a clear indication to update your PHP version.

To avoid facing any problems, it is necessary that you resolve any issues before upgrading your PHP version. We suggest you follow the process in the following order to make things easier.

  • Delete any plugins that are not in use.
  • Check if there are any compatibility issues with the plugins and themes using PHP Compatibility Checker.
  • Consider using a different plugin in case the latest version of plugins isn’t compatible with 7.3 or higher.
