What are the potential pitfalls of using ENUM data type in PHP and MySQL databases?

One potential pitfall of using ENUM data type in PHP and MySQL databases is that it can limit the flexibility of your database schema. If you need to add or remove values from the ENUM list, it can be a cumbersome process. To solve this issue, consider using a separate lookup table with foreign key constraints instead of ENUM. 

// Example of using a lookup table instead of ENUM
// Create a table for storing possible values
CREATE TABLE status (
    id INT PRIMARY KEY,
    name VARCHAR(50)
);

// Insert some sample values
INSERT INTO status (id, name) VALUES (1, 'Active');
INSERT INTO status (id, name) VALUES (2, 'Inactive');

// Create a table that references the status table
CREATE TABLE users (
    id INT PRIMARY KEY,
    name VARCHAR(50),
    status_id INT,
    FOREIGN KEY (status_id) REFERENCES status(id)
);

// Insert data into the users table
INSERT INTO users (id, name, status_id) VALUES (1, 'John Doe', 1);
INSERT INTO users (id, name, status_id) VALUES (2, 'Jane Smith', 2);
