set_exception_handler('exception_handler');register_shutdown_function('shutdown_handler');
function assert_callcack($file, $line, $message) {
throw new Customizable_Exception($message, null, $file, $line);}function error_handler($errno, $error, $file, $line, $vars) {
if ($errno === 0 || ($errno & error_reporting()) === 0) {
return;
}
throw new Customizable_Exception($error, $errno, $file, $line);}function exception_handler(Exception $e) {
// Do what ever!
echo '

exit;}function shutdown_handler() {
try {
if (null !== $error = error_get_last()) {
throw new Customizable_Exception($error['message'], $error['type'], $error['file'], $error['line']);
}
} catch (Exception $e) {
exception_handler($e);
}}class Customizable_Exception extends Exception {
