On this page you find information about the implemented php standards recommendations in Nextcloud.
This standard has been deprecated and will be removed from Nextcloud. Please see the PSR-4 section instead.
PSR-3: Logger Interface
New in version 19.
The dependency injection container can inject an instance of a
\Psr\Log\LoggerInterface. This is merely a wrapper of the existing (and strongly typed)
\OCP\ILogger. Apps may still use the Nextcloud logger, but the PSR-3 implementation shall easy the integration of 3rd party libraries that require the PSR-3 logger.
Changed in version 21: Nextcloud ships version 1.1.3
Changed in version 23: Nextcloud ships version 1.1.4
The PSR-4 standard describes how class files should be named, so Nextcloud can automatically load them. See the classloader docs for details.
PSR-11: Container Interface
New in version 20.
The dependency injection container follows the PSR-11 container interface, so you may type-hint
\Psr\Container\ContainerInterface whenever you want an instance of a container and use
has($id) to check for existence and
get($id) to retrieve an instance of a service. See the dependency injection docs for details.
