What are the advantages of using MySQL date or datetime data types instead of storing dates as strings in a specific format?

Storing dates as strings in a specific format can lead to inconsistencies, errors, and difficulties when performing date-related operations such as sorting or comparing dates. Using MySQL date or datetime data types ensures data integrity, allows for efficient date manipulation and querying, and simplifies date formatting and calculations. 

// Create a table with a column of type DATE
$sql = "CREATE TABLE example_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    event_date DATE
)";

// Insert a date into the table
$date = date("Y-m-d"); // Get the current date in YYYY-MM-DD format
$sql = "INSERT INTO example_table (event_date) VALUES ('$date')";

// Retrieve and display dates from the table
$sql = "SELECT event_date FROM example_table";
$result = mysqli_query($conn, $sql);
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['event_date'] . "<br>";
}
