PHP beginners can ensure that their code remains PHP conformant when integrating additional functionalities like captchas by following best practices such as validating user input, sanitizing data, and using secure coding techniques. Additionally, they should regularly update their PHP version to the latest stable release to benefit from security patches and improvements. 

// Example of validating user input for a captcha integration
$captcha_response = $_POST['g-recaptcha-response'];

if (empty($captcha_response)) {
    // Handle error, display message or redirect
} else {
    // Proceed with captcha validation
}
