logging-example

An example of the iterator interface and splat operator (variadics).

Where to look

src/Logger_Collection.php
implements iterator and uses a variadic arg in the constructor. Note that the constructor is type hinted for Logger_Interface.

src/Plugin.php
line 24: Creates the Logger_Collection object and passes a bunch of objects. Note that all objects it passes implement the Logger_Interface.
line 32: Handles calls to the logger. Note you could also just logger_example()->log( $message, $type, $id )
line 48: In this method, the iterator actually iterates. Because we know the object type we will have available on each loop, we know the available methods.
