Functions for error handling.

Code

function _drupal_error_handler_real($error_level, $message, $filename, $line, $context) {
  if ($error_level & error_reporting()) {
    $types = drupal_error_levels();
    list($severity_msg, $severity_level) = $types[$error_level];
    $backtrace = debug_backtrace();
    $caller = Error::getLastCaller($backtrace);

    // We treat recoverable errors as fatal.
    $recoverable = $error_level == E_RECOVERABLE_ERROR;
    // As __toString() methods must not throw exceptions (recoverable errors)
    // in PHP, we allow them to trigger a fatal error by emitting a user error
    // using trigger_error().
    $to_string = $error_level == E_USER_ERROR && substr($caller['function'], -strlen('__toString()')) == '__toString()';
    _drupal_log_error(array(
      '%type' => isset($types[$error_level]) ? $severity_msg : 'Unknown error',
      // The standard PHP error handler considers that the error messages
      // are HTML. We mimick this behavior here.
      '@message' => Markup::create(Xss::filterAdmin($message)),
      '%function' => $caller['function'],
      '%file' => $caller['file'],
      '%line' => $caller['line'],
      'severity_level' => $severity_level,
      'backtrace' => $backtrace,
      '@backtrace_string' => (new \Exception())->getTraceAsString(),
    ), $recoverable || $to_string);
