The error and exception handlers of AloFramework

3.0 2016-11-07 21:47 UTC


A powerful error and exception handler of AloFramework. It can automatically log errors and exceptions if an object implementing the \Psr\Log\LoggerInterface is passed on and will echo output based on your server's error reporting settings, altering its format depending on whether an error is raised during a HTTP or CLI call.

Installation is available via Composer:

composer require aloframework/handlers


  • To enable the exception handler call \AloFramework\Handlers\ExceptionHandler::register()
  • To enable the error handler call \AloFramework\Handlers\ErrorHandler::register()
  • To enable the shutdown handler call \AloFramework\Handlers\ShutdownHandler::register()


Every error and exception has to be logged in this package. You can supply your own logger to have more control; if you don't, aloframework/log will be used with its default settings.
