1. When querying information from the same database using SELECT, use a join statement to get all the information you need at once, without writing multiple mysql_query/while/mysql_fetch_array statements.
2. If you call a database connection in multiple files, create a connection.php file to save your connection variables, and include this file where needed.
3. For small projects, write all of your functions in a file, if a large project is written in the object, then include this file where needed.
4. If your include file is out of control, you can create an include file that contains all the. inc files, and then include this one included file where you need it.
5. Write a document for your code, and you'll need it when you look at the code 3 months later.
6, code layout, nothing is more important than readability.
7, separate the logic and the presentation layer.
