Use PHP to implement the 24 o'clock game on the WeChat public platform. The server is built as SAE, so many statements are different from MYSQL. The 24 o'clock database is stored in 24data. The results are first calculated using python and then stored in a local txt file and finally poured into it. SAE's MYSQL records all four numbers with solutions. WeChat ID can be added: 24 o'clock.
