PHP is a flexible language that can run in different environments like, for instance, a Web server or a command-line interface shell console.

Developers can create applications that adapt to the different environments in which PHP may be running.

This package helps developers who want to adapt to the different environments PHP is running.

It checks some environment values and returns the information of the specific environment in which it is running.

Using this package, developers only need to adapt their code depending on the environment type that this package returns.
