Whoops – A Library For Better PHP Error Reporting
Whoops is a PHP library for handling errors and debugging them much easily.
The library provides stack-based error handling with a good-looking error interface.
It has a simple API for dealing with exceptions, trace frames + their data and can integrate with any framework (ready-to-use integrations exist for end and Silex).
Whoops has no dependencies to run and has the ability to open referenced files directly in your editor and IDE.
