Community support for PHP 7.3 is ending on 6 December 2021
Date de publication : 24 août, 2021
Because PHP 7.3 extended support on Linux and Windows will end on 6 December 2021, any applications hosted on Azure App Service that are still using it will not be supported after 6 December 2021. Your applications will continue to run unchanged but won't receive any patches after 6 December 2021, since PHP will no longer be providing them.
To minimize risk and potential security vulnerabilities, follow the steps to update your applications to PHP 7.4 before 6 December 2021.
