What are some potential pitfalls when using PHP to build a Point of Interest page with MySQL data?

One potential pitfall when using PHP to build a Point of Interest page with MySQL data is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements or parameterized queries when interacting with the database. 

// Example of using prepared statements to prevent SQL injection

// Assuming $pdo is your PDO database connection object

$poi_id = $_GET['poi_id'];

$stmt = $pdo->prepare('SELECT * FROM points_of_interest WHERE id = :poi_id');
$stmt->bindParam(':poi_id', $poi_id, PDO::PARAM_INT);
$stmt->execute();

$poi = $stmt->fetch(PDO::FETCH_ASSOC);

// Now you can safely use the $poi data in your page
