/**
|
|
* Error Handler.
|
|
*
|
|
* Captures and handles all unhandled exceptions. Displays helpful framework errors when debug > 1.
|
|
* When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown
|
|
* and it is a type that ErrorHandler does not know about it will be treated as a 500 error.
|
|
*
|
|
* ### Implementing application specific exception handling
|
|
*
|
|
* You can implement application specific exception handling in one of a few ways:
|
|
*
|
|
* - Create a AppController::appError();
|
|
* - Create an AppError class.
|
|
*
|
|
* #### Using AppController::appError();
|
|
*
|
|
* This controller method is called instead of the default exception handling. It receives the
|
|
* thrown exception as its only argument. You should implement your error handling in that method.
|
|
*
|
|
* #### Using an AppError class
|
|
*
|
|
* This approach gives more flexibility and power in how you handle exceptions. You can create
|
|
* `app/libs/app_error.php` and create a class called `AppError`. The core ErrorHandler class
|
|
* will attempt to construct this class and let it handle the exception. This provides a more
|
|
* flexible way to handle exceptions in your application.
|
|
*
|
|
* Finally, in your `app/config/bootstrap.php` you can configure use `set_exception_handler()`
|
|
* to take total control over application exception handling.
