# Runtimes

> Laravel Cloud supports PHP 8.2 through 8.5 for Laravel and Symfony applications.

## Overview

Laravel Cloud uses the PHP runtime for Laravel and Symfony applications. The runtime determines which PHP versions, extensions, and platform features are available to your application.

## PHP runtime

**Supported versions:** PHP 8.2, 8.3, 8.4, and 8.5. PHP 8.5 is the default for new environments.

To select your PHP version, open your environment's General Settings page and choose the version under the Runtime section. A re-deployment is required for the change to take effect.

<Note>
  PHP 8.5 is generally available, but the `pdo_sqlsrv` extension is temporarily unavailable until the upstream project adds 8.5 support. Use PHP 8.2, 8.3, or 8.4 if you need that extension today.
