Display error messages and exceptions using xdebug quite comfortable.
But besides the output is the task to caloghirou encountered an error and send a mail to the administrator.
Put your handler using set_error_handler and set_exception_handler.
The processors perform all necessary actions, in set_error_handler then do return false and start the xdebug error handler that displays a message on the screen, and for the exception handler there is no such mechanism to call the previous handler is impossible.
Has anyone faced such a problem?
