Tblog is an open source blog system developed based on php+pdo+sqlite3. It does not need to be installed, it can be used directly in the space that supports pdo. It is as convenient as using asp+access. The blog system includes many functions such as log publishing, column definition, mood recording, friendly links, etc. It is a good choice for you to develop, learn and build your own blog system. The code of this system is simple to write and easy to understand. It is a good example for many programmers to understand and learn the pdo extension in php and the database sqlite3. Finally, I hope everyone likes this blog system and provides suggestions for improvements. Backend management address:/admin/ Default backend account and password: admin,admin
