Sqlite + php + ajax instant chat system (ajax persistent connection) I. sqliteajax

Talking nonsense: Today, lol encountered a poor product, and the technology was really good. After that, I was told that the guy told me to ask him for help and he would play. I scolded him for being silly. I hung up and watched them lose. Sometimes, when someone else is in trouble, I start with something strong!

Idea: sqlite: database data, used to save chat records; php links to the database, receives ajax transmission data, and returns processing results; ajax asynchronously obtains chat data and asynchronously updates chat records;

For the database classes used, refer to the previous blog.
