Error HandlerΒΆ

Class \TYPO3\CMS\Core\Error\ErrorHandler is the default error handler in TYPO3.


  • Can be registered for all PHP errors or for only a subset of the PHP errors which will then be handled by an error handler.
  • Displays error messages as flash messages in the Backend (if exceptionHandler is set to \TYPO3\CMS\Core\Error\DebugExceptionHandler). Since flash messages are integrated in the Backend template, PHP messages will not destroy the Backend layout.
  • Displays errors as TsLog messages in the adminpanel.
  • Logs error messages to \TYPO3\CMS\Core\Utility\GeneralUtility::syslog() which is able to write error messages to a file, to the web server's error_log, the system's log and it can send error- and exception-messages by mail. \TYPO3\CMS\Core\Utility\GeneralUtility::syslog() offers a hook and can be extended by userdefined logging methods.
  • Logs error messages to the sys_log table. Logged errors are displayed in the belog extension (ADMIN TOOLS > Log). This will work only with an existing DB connection.
