PHP 7.4 goes end of life (EOL) on the 28 November 2022 meaning known security flaws will no longer be fixed and sites are exposed to significant security vulnerabilities.
It is important to update them to a newer version. We would recommend updating to either:
- 8.0 supported until 26 November 2023
- 8.1 supported until 25 November 2024
New major PHP versions bring with it a number of new features and some incompatibilities. These should be tested before switching PHP versions in production environments. You may need to get your developers to update some code, check plug-ins and app versions for the new PHP supportability:
WordPress 5.6 to 5.9 state that they have added “beta support” for PHP 8.0 and 8.1 however no one know when it will be out of beta status. Beta support means that the compatibility of WordPress with PHP is still being tested. We would usually advise not to use it on a production server until it is fully supported by WordPress.
Not sure what version your server is on? Maybe it’s time for a Server Audit so you have a full picture of your infrastructure – We produce a traffic light report telling you the good, the bad and the ugly…
