This code seems to be duplicated across your project.

            // Multiple lines detected, adding three backticks and newlines
            $markdown .= '```' . "\n" . $pre_content . "\n" . '```';
        } else {
            // One line of code, wrapping it on one backtick.
            $markdown .= '`' . $pre_content . '`';
        }

        return $markdown;
    }
