What are some common errors or mistakes to avoid when integrating PHP scripts with existing content management systems like PHP Nuke?

One common mistake to avoid when integrating PHP scripts with existing content management systems like PHP Nuke is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection attacks. To solve this issue, always use prepared statements or parameterized queries when interacting with the database to prevent malicious input from being executed. 

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