1 bootstrap.inc | _backdrop_exception_handler($exception) |
Provides custom PHP exception handling.
Uncaught exceptions are those not enclosed in a try/catch block. They are always fatal: the execution of the script will stop as soon as the exception handler exits.
Parameters
$exception: The exception object that was thrown.

Code
function _backdrop_exception_handler($exception) {
require_once BACKDROP_ROOT . '/core/includes/errors.inc';
try {
// Log the message to the watchdog and return an error page to the user.
_backdrop_log_error(_backdrop_decode_exception($exception), TRUE);
}
catch (Exception $exception2) {
// Default the status code to 500 before any other code is run. This will
// make any FATAL errors return 500 responses instead of 200, and also
// account for cases where an exception was thrown before the 500 status
// could be set (e.g. while loading a maintenance theme from cache).
backdrop_add_http_header('Status', '500 Internal Server Error');
// Another uncaught exception was thrown while handling the first one. If we
// are displaying errors, then do so with no possibility of a further
// uncaught exception being thrown.
