What are the potential drawbacks of creating a new database table for each user's selection in a PHP shopping cart system?

Creating a new database table for each user's selection in a PHP shopping cart system can lead to scalability issues and inefficient database management. Instead, it is recommended to have a single table to store all user selections, with a column to differentiate between users. This approach allows for easier querying, maintenance, and scalability of the database.

// Example of a single table structure to store user selections in a shopping cart system

CREATE TABLE user_selections (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    product_id INT,
    quantity INT,
    price DECIMAL(10,2),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
