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.
