What to Do Before Updating PHP
Here are a few things you have to do before updating PHP.
Backup Your Site
Before updating your WordPress, it’s always advised to create a backup. The same is applicable to updating the PHP version of your WordPress website. Here are two big reasons why creating a backup before updating to the latest PHP is very important.
- WordPress themes and plugins are written in PHP. If any of the plugins or your theme is poorly scripted, there will be compatibility issues once the update is done.
- There are chances that something might go wrong during the updating process. A common example is the loss of an internet connection. As small as the issue looks, it could lead to a catastrophic outcome in some cases.
Update Plugins and Themes
There are chances that your Themes & plugins might not be compatible with the current version of PHP.
To prevent this from happening, you have to update your WordPress plugins and themes to the latest versions.
To proceed, log in to your WordPress dashboard. Next, go to Dashboard >> Updates. Here, install all available updates.
Check PHP Compatibility
Now as you have the latest version of themes and plugins, you need to test them by using the PHP Compatibility Checker plugin. Please check the following guidelines to learn how to install WordPress plugins.
After successfully activating the plugin, go to Tools >> PHP Compatibility. After that, select the latest version of PHP.
You may choose to scan active plugins/themes only or scan everything. Lastly, click on the Scan site button.
The plugin take-overs from here. It scans and identifies all the compatibility issues between PHP and all themes/plugins.
If you face problems, you may either stop using the plugin option and search for an alternative plugin or contact the plugin developer to fix the issues it has.
Note: At the time of creating this post, the plugin only scans up to PHP 7.3 version. But in the future, if you need to check for compatibility with PHP 8 and above versions, we recommend testing the update on a staging environment before going on a live site.
Now that you know the benefits of updating to the latest version of PHP and hopefully have a backup of your site, let’s show you how to update PHP in WordPress.

For plugins, deactivate all the plugins and check if your site comes back or not. If it works, then one of your plugins is the culprit. To find the faulty plugin, begin activating your plugins one by one. Each time, confirm whether your site is working or not.
