What are the advantages of using DATE or TIMESTAMP data types over VARCHAR for date storage in PHP?

Using DATE or TIMESTAMP data types for date storage in PHP offers several advantages over using VARCHAR. 1. Data integrity: DATE and TIMESTAMP data types ensure that only valid dates can be stored in the database, preventing any incorrect or invalid dates from being entered. 2. Efficiency: Storing dates as DATE or TIMESTAMP data types allows for more efficient storage and retrieval of date information, as the database can optimize its operations based on the data type. 3. Built-in functions: DATE and TIMESTAMP data types come with built-in functions in PHP that make it easier to manipulate and format date values. 

// Example of creating a table with DATE data type for date storage
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

// Create table with DATE data type for date storage
$sql = "CREATE TABLE dates (
  id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  event_date DATE
)";

if ($conn->query($sql) === TRUE) {
  echo "Table created successfully";
} else {
  echo "Error creating table: " . $conn->error;
}

$conn->close();
