What is the recommended data type for storing dates in MySQL when planning to group by months in PHP queries?

When planning to group by months in PHP queries in MySQL, it is recommended to store dates using the DATE data type. This allows for easy extraction of month and year components for grouping purposes. By using the DATE data type, you can efficiently query and group data by months without the need for complex date manipulation functions. 

// Example of creating a table with a DATE column in MySQL
CREATE TABLE example_table (
    id INT PRIMARY KEY,
    date_column DATE
);

// Example of inserting data into the table
INSERT INTO example_table (id, date_column) VALUES (1, '2022-01-15'), (2, '2022-02-20'), (3, '2022-03-10');

// Example of querying and grouping data by month
SELECT MONTH(date_column) AS month, COUNT(*) AS total
FROM example_table
GROUP BY MONTH(date_column);
