Why is maintaining consistent ID numbering important in PHP applications, especially in scenarios with a large number of users?

Maintaining consistent ID numbering is important in PHP applications, especially in scenarios with a large number of users, to ensure data integrity and avoid conflicts or inconsistencies in the database. One way to achieve this is by using auto-incremented primary keys in database tables, which guarantees unique and sequential IDs for each record. 

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL
);
