What resources or documentation can be helpful for PHP beginners to avoid common pitfalls in coding?

One common pitfall for PHP beginners is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection attacks. To avoid this, always use prepared statements when interacting with a database to prevent malicious input from being executed as SQL queries. Example: 

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

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');

// Bind the user input to the placeholders
$stmt->bindParam(':username', $_POST['username']);

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

// Fetch the results
$results = $stmt->fetchAll();
