What best practices should be followed when using bindParam vs bindValue in PDO for database queries in PHP?

When using PDO for database queries in PHP, it is generally recommended to use bindParam over bindValue for better performance and security. bindParam binds a variable by reference, allowing the value to be updated before the query is executed, while bindValue binds a value directly, making it static. This can be important when working with dynamic data or loops. 

// Using bindParam for better performance and security
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$id = 1;
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
