Si utiliza el único punto de método de entrada. (Index.php) Puedo recomendar esto para su gestión de errores:
versión corta:
ob_start();
register_shutdown_function('shutdownHandler');
include('something');
define(CLEAN_EXIT, true);
function shutdownHandler() {
if(!defined("CLEAN_EXIT") || !CLEAN_EXIT) {
$msg = "Script stopped unexpectedly: ".ob_get_contents();
//Handle premature die()/exit() here
}
}
medidas adicionales y más detalladas:
Aproximadamente mi manera de hacerlo. Tengo aún más cosas que mostrar aquí (manejo de transacciones de bases de datos/reversión/envío de correos electrónicos/registros de escritura/visualización de mensajes de error amigables/informes de errores del usuario/etc), pero esta es la idea básica detrás de todo).
Espero que ayude a alguien.
<?php

//starting output buffering. (fatalErrorHandler is optional, but I recommend using it)
ob_start('fatalErrorHandler');
//Execute code right at the end. Catch exit() and die() here. But also all other terminations inside PHPs control

//handling other errors: Also optional
set_error_handler('errorHandler');

//Include of offensive code
include(...);

//Handling exception. Be careful to not raise exceptions here again. As you can end up in a cycle.

Bueno, es posible reescribiendo el script mientras lo lees. El siguiente ejemplo tokeniza la entrada y reescribe la salida ($ code) y el código $ die a php_exit ($ code): EDIT: stackoverflow no me permite agregar código aquí; consulte esta publicación para obtener inspiración: http://stackoverflow.com/questions/31182968/token-get-all-back-to-php-source-how-to – user1135940
