What are the advantages of using Date data type over INT for storing dates in a PHP application?

Using the Date data type over INT for storing dates in a PHP application provides several advantages. Date data type allows for easier manipulation and comparison of dates, as it provides built-in functions for date formatting, arithmetic, and comparison. It also helps ensure data integrity by enforcing date validation rules, preventing invalid dates from being stored in the database. Additionally, using Date data type can improve code readability and maintainability by clearly indicating the purpose of the stored data.

// Example of using Date data type in PHP
$date = new DateTime('2022-12-31');
echo $date->format('Y-m-d'); // Output: 2022-12-31
