What are the advantages of using PDO and Prepared Statements for SQL queries involving date calculations in PHP?

When dealing with SQL queries involving date calculations in PHP, using PDO and Prepared Statements offers several advantages. Prepared Statements help prevent SQL injection attacks by separating SQL logic from user input, while PDO provides a consistent interface for accessing various databases. Additionally, prepared statements can improve performance by allowing the database to optimize query execution. 

// Using PDO and Prepared Statements for SQL queries involving date calculations
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$date = "2022-01-01";
$statement = $pdo->prepare("SELECT * FROM mytable WHERE date_column > DATE_SUB(:date, INTERVAL 1 MONTH)");
$statement->bindParam(':date', $date);
$statement->execute();

$results = $statement->fetchAll(PDO::FETCH_ASSOC);

foreach ($results as $row) {
    // Handle each row as needed
}
