Plop was originally a port of Python's logging module to PHP, and so its API bears many similarities with that of its Python counterpart. But as time went by, the code underwent several major rewrites to make it easier to use and maintain.
Plop aims at providing an efficient logging API while being more feature-complete than PEAR's Log package and more user-friendly than Apache's log4php. It is also aimed at simplicity and makes for a lightweight alternative to other PHP logging projects like Monolog.
The code is compatible with various PHP Standards Recommendation such as PSR-2, PSR-3 & PSR-4.
