Functions for error handling.

Code

  if ($error_level & error_reporting()) {
    $types = drupal_error_levels();
    list($severity_msg, $severity_level) = $types[$error_level];
    $caller = _drupal_get_last_caller(debug_backtrace());

    if (!function_exists('filter_xss_admin')) {
      require_once DRUPAL_ROOT . '/includes/common.inc';
    }

    // We treat recoverable errors as fatal.
    _drupal_log_error(array(
      '%type' => isset($types[$error_level]) ? $severity_msg : 'Unknown error',
      // The standard PHP error handler considers that the error messages
      // are HTML. We mimick this behavior here.
      '!message' => filter_xss_admin($message),
      '%function' => $caller['function'],
      '%file' => $caller['file'],
      '%line' => $caller['line'],
