How can PHP frameworks help in managing security measures and preventing vulnerabilities in web applications?

PHP frameworks can help in managing security measures and preventing vulnerabilities in web applications by providing built-in security features such as input validation, output encoding, CSRF protection, and secure session handling. These frameworks also follow best practices for secure coding and often have security patches and updates readily available. Example:

// Using Laravel framework to prevent SQL injection
$user = DB::select("SELECT * FROM users WHERE id = ?", [$id]);
