What are some best practices for structuring tables in PHP to avoid potential pitfalls with different data types?

When structuring tables in PHP, it is important to define the appropriate data types for each column to avoid potential pitfalls such as data truncation, incorrect sorting, or unexpected behavior. To ensure data integrity and consistency, it is recommended to use the correct data types for each column, such as INT for integers, VARCHAR for variable-length strings, and DATE for dates.

CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL,
    birthdate DATE
);
