README

This library is used by other f2/*-libraries for basic things such as configuration discovery, common exception classes and performance optimizations.

F2::events(): F2\Common\Contracts\EventServiceInterface

Provides the central event dispatcher:

Listening for events

F2::events()->on('some_event_name', function(F2\Common\Contracts\EventInterface $event) {});

Un-listening

F2::events()->off('some_event_name', $handler);

Emitting events

F2::events()->emit(new F2\Common\Event('some_event_name', ['some' => 'data']));

F2::config(string $configName, $defaultValue = null): mixed

Retrieve a configuration value from these sources in order:

1. $GLOBALS['f2']['config'][$configName]

2. F2::config()->env($configName)

3. $GLOBALS['f2']['config']['defaults'][$configName]

4. Config defaults provided by Manifest classes.

F2::env(string $name): string

Retrieve a configuration value from the environment. Will load a .env file from the project root. If a value is not found, it will load default.env from project root and check for the value there.
