/**
* Error Handler
*
* This is the custom error handler that is declared at the (relative)
* top of CodeIgniter.php. The main reason we use this is to permit
* PHP errors to be logged in our own log files since the user may
* not have access to server logs. Since this function effectively
* intercepts PHP errors, however, we also need to display errors
* based on the current error_reporting level.
* We do that with the use of a PHP error template.
*
* @param int $severity
* @param string $message
* @param string $filepath
* @param int $line
* @return void

// This can't be done within the $_error->show_php_error method because
// it is only called when the display_errors flag is set (which isn't usually
// the case in a production environment) or when errors are ignored because
// they are above the error_reporting threshold.
