PHP
App Service on Linux supports PHP as a runtime stack built-in image.
PHP Update Policy - App Service upgrades the underlying PHP runtime of your application as part of the regular platform updates. As a result of this regular update process, your application will be automatically updated to the latest patch version of PHP available in the platform. For more information about current supported PHP versions check Support Timeline.
