Are there other security measures besides closing register globals that should be implemented in PHP?

One important security measure besides closing register globals in PHP is to sanitize user input to prevent SQL injection attacks. This can be done by using prepared statements with parameterized queries when interacting with a database. Additionally, implementing input validation and output escaping can help prevent cross-site scripting (XSS) attacks. 

// Example of using prepared statements to prevent SQL injection
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();
