Chat program using line writing (Part 1)_PHP tutorial

In the early stage, I saw the very small version of the chat program of mdjwq@yeah.net and Daoxiangju’s Red Dragonfly. I read their code carefully and felt that this was a rare code, especially for those who had just read it. For beginners, some techniques are used in the program, which are of great reference value. Based on their code and my own experience, I added some functions (management of online personnel, etc.), and changed the implementation method from TXT to MySQL (the best combination with PHP) . All programs are in All local debugging has passed. I hope that netizens who have their own chat programs can use it directly. After my personal homepage is completed, it will be used in conjunction with the forum (the forum has been fully installed, and other content will also be migrated from chinaren to oso), and an Oracle (large website database platform) and MySQL will be opened (The best combination with PHP)Database administrator’s information discussion board.
Forum information table:
create table lt_t_online /* Record online personnel information*/
( /* Name, last speaking time, IP address, status (0 online, 1 offline) */
lt_username varchar(12)                                                                                                                                                                                                                                                                                                    _state char(1) not null
);

create table lt_t_content / * Chat information table */
( /* Speaker, object, confidentiality level, expression, color, content, time */
lt_speaker varchar(12) not null,
lt_speaked varchar(12) not null,
lt_secrecy char(1) not null,
