What are the potential security risks in implementing a tab system in PHP for a project like a driving school?

One potential security risk in implementing a tab system in PHP for a driving school project is the vulnerability to SQL injection attacks if user input is not properly sanitized. To mitigate this risk, you should use prepared statements or parameterized queries to interact with the database, which helps prevent SQL injection attacks. 

// Using prepared statements to prevent SQL injection

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=driving_school', 'username', 'password');

// Prepare a SQL statement
$stmt = $pdo->prepare('SELECT * FROM students WHERE id = :id');

// Bind parameters and execute the statement
$stmt->bindParam(':id', $_GET['id']);
$stmt->execute();

// Fetch the results
$result = $stmt->fetch(PDO::FETCH_ASSOC);

// Use the results
echo $result['name'];
