What are some common pitfalls when trying to store data in a database using PHP?

One common pitfall when storing data in a database using PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely insert data into the database. 

// Connect to database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Sanitize user input
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);

// Prepare statement
$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);

// Execute statement
$stmt->execute();
