PHP 8.5 is now available on Azure App Service for Linux across all public regions. You can create a new PHP 8.5 app through the Azure portal, automate it with the Azure CLI, or deploy using ARM/Bicep templates.

PHP 8.5 brings several useful runtime improvements. It includes better diagnostics, with fatal errors now providing a backtrace, which can make troubleshooting easier. It also adds the pipe operator (|>) for cleaner, more readable code, along with broader improvements in syntax, performance, and type safety. You can take advantage of these improvements while continuing to use the deployment and management experience you already know in App Service.

For the full list of features, deprecations, and migration notes, see the official PHP 8.5 release page: https://www.php.net/releases/8.5/en.php
