Are there any PHP libraries or tools that can assist with form validation and input sanitization to prevent security vulnerabilities?

To prevent security vulnerabilities such as SQL injection or cross-site scripting attacks, it is essential to properly validate and sanitize user input in PHP forms. This can be achieved using PHP libraries or tools that provide functions for form validation and input sanitization. By using these tools, you can ensure that the data submitted by users is safe and secure. 

// Example using the filter_input function for input validation and sanitization
$username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);
$email = filter_input(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL);

if (!$username || !$email) {
    // Handle validation errors
} else {
    // Proceed with safe data
}
