How can one ensure proper syntax when using PDO Prepared Statements in PHP?

To ensure proper syntax when using PDO Prepared Statements in PHP, make sure to use placeholders in the SQL query and bind the values to these placeholders using the PDOStatement::bindParam() method. This helps prevent SQL injection attacks and ensures that the syntax of the query remains correct even when dealing with user input. 

// Example code snippet to ensure proper syntax with PDO Prepared Statements
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$name = "John Doe";
$age = 30;

$stmt = $pdo->prepare("INSERT INTO users (name, age) VALUES (:name, :age)");
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->bindParam(':age', $age, PDO::PARAM_INT);

$stmt->execute();
