PHP 8.0 goes end of life on the 26 November 2023. 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:

• 8.1 supported until 25 November 2024
• 8.2 supported until 08 December 2025
  

This new minor version brings with it a number of new features and a few incompatibilities that should be tested for before switching PHP versions in production environments.

You may need to get your developers to update code, check plug-ins and app versions for supportability:

• Deprecated Features when migrating from 8.0.x to PHP 8.1.x

WordPress is still only showing “beta support” for anything PHP 8.0 or above, as WordPress say:

WordPress is not fully compatible with PHP 8.0 or 8.1. All remaining known PHP 8.1 issues are deprecation notices.

Please note, a deprecation notice is not an error, but rather an indicator of where additional work is needed for compatibility before PHP 9 (i.e. when the notices become fatal errors). With a deprecation notice, the PHP code will continue to work and nothing is broken.

At the time of writing PHP 8.2 for wordpress was still waiting on the dev notes.

PHP 7.3 goes end of life (EOL) on the 6th December 2021 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:

• 7.4 supported until 28 November 2022
• 8.0 supported until 26 November 2023

As with any upgrade you will want to test your site on the new version before migrating. You may need to get your developers to update some code, check plugins and app versions for the new PHP supportability:

• Deprecated Features when migrating from 7.3 to 7.4
• Deprecated Features when migrating from 7.4 to 8.0

PHP 8 is still very new and untested but a lot of CMS’s are supporting it. WordPress 5.6 has stated that they are “Beta compatible” with PHP 8.0 however there is still a way to go for a number of plugins.

• 7.2 supported until 30 November 2020
• 7.3 supported until 6 December 2021

As with any upgrade you will want to test your site on the new version before migrating. You may need to get your developers to update some code, check plugins and app versions for the new PHP supportability.

If you love a pie chart, Jordi Boggiano has provided this great overview of the PHP versions out there.

Upgrade from PHP 7.1 before the 1st December 2019.
