What are some common methods for integrating a points system into a PHP login system?

One common method for integrating a points system into a PHP login system is to create a database table to store user points and update it accordingly when a user logs in or performs certain actions on the site. You can then retrieve and display the user's points on their profile page or throughout the site. 

// Example code to update user points in a PHP login system

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

// Update user points when user logs in
$user_id = $_SESSION['user_id'];
$sql = "UPDATE users SET points = points + 10 WHERE id = $user_id";
$conn->query($sql);

// Retrieve user points
$sql = "SELECT points FROM users WHERE id = $user_id";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo "Points: " . $row["points"];
  }
} else {
  echo "0 points";
}

$conn->close();
