27 * A generic ErrorHandler for the PHP engine.
29 * Provides five bit fields that control how errors are handled:
30 * - thrownErrors: errors thrown as \ErrorException
31 * - loggedErrors: logged errors, when not @-silenced
32 * - scopedErrors: errors thrown or logged with their local context
33 * - tracedErrors: errors logged with their stack trace
34 * - screamedErrors: never @-silenced errors
36 * Each error level can be logged by a dedicated PSR-3 logger object.
37 * Screaming only applies to logging.
38 * Throwing takes precedence over logging.
39 * Uncaught exceptions are logged as E_ERROR.
40 * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
41 * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
42 * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
43 * As errors have a performance cost, repeated errors are all logged, so that the developer
44 * can see them and weight them as more important to fix than others of the same level.
