What resources or online articles can provide comprehensive information on PHP security best practices and common pitfalls to avoid?

To ensure PHP security best practices and avoid common pitfalls, it is important to follow guidelines such as validating user input, using parameterized queries to prevent SQL injection, avoiding the use of deprecated functions, and implementing proper session management techniques. 

// Validate user input to prevent malicious code injection
$user_input = $_POST['input'];
$clean_input = htmlspecialchars($user_input);

// Use parameterized queries to prevent SQL injection
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();

// Avoid deprecated functions like mysql_query
$result = mysqli_query($conn, $query);

// Implement proper session management techniques
session_start();
$_SESSION['user_id'] = $user_id;
