What are some potential pitfalls when using enums in PHP database tables?

One potential pitfall when using enums in PHP database tables is that it can limit the flexibility of your application by restricting the possible values that can be stored in a column. To solve this issue, you can use a separate lookup table to store the enum values and then reference them in your main table using foreign keys. 

// Create a lookup table for enum values
CREATE TABLE enum_values (
    id INT PRIMARY KEY,
    value VARCHAR(50)
);

// Insert enum values into the lookup table
INSERT INTO enum_values (id, value) VALUES (1, 'Value1');
INSERT INTO enum_values (id, value) VALUES (2, 'Value2');

// Use foreign keys to reference enum values in your main table
CREATE TABLE main_table (
    id INT PRIMARY KEY,
    enum_value_id INT,
    FOREIGN KEY (enum_value_id) REFERENCES enum_values(id)
);
