If you visit your WordPress site and everything appears to be functioning and displaying as it should, your PHP is likely working. However, if there are any issues or an update is required, you can find them listed under the Site Health tool from your WordPress dashboard.
Also, to ensure a PHP version works with your site, it’s important to check the PHP compatibility of your themes and plugins. For this, you may want to use a plugin such as PHP Compatibility Checker. Once installed, it will display errors and warnings related to your PHP version and WordPress compatibility. However, as we mentioned earlier, this plugin hasn’t been tested with the latest versions of WordPress.
