In what scenarios would it be beneficial to use PDO::PARAM_INT over other data types in PHP prepared statements?

When working with integer values in PHP prepared statements using PDO, it is beneficial to use PDO::PARAM_INT to ensure that the integer data is properly bound and executed in the SQL query. This parameter type helps prevent SQL injection attacks and ensures that the integer data is treated as an integer by the database, avoiding any potential type casting issues. 

// Example of using PDO::PARAM_INT in a prepared statement
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$id = 123; // Integer value to bind

$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();

$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
