What are the best practices for maintaining code readability and organization in PHP scripts, especially when incorporating third-party functions like Captcha?

When incorporating third-party functions like Captcha in PHP scripts, it is important to maintain code readability and organization by separating the logic for the Captcha functionality from the rest of the script. One way to achieve this is by creating a separate function or class specifically for handling the Captcha validation. This helps keep the code clean and makes it easier to maintain and troubleshoot in the future. 

// Separate function for Captcha validation
function validateCaptcha($captchaResponse) {
    // Validate Captcha response using the third-party library
    if ($captchaResponse) {
        // Captcha validation successful
        return true;
    } else {
        // Captcha validation failed
        return false;
    }
}

// Main script
$captchaResponse = $_POST['g-recaptcha-response'];

if (validateCaptcha($captchaResponse)) {
    // Captcha validation successful, proceed with the rest of the script
    // Your code here
} else {
    // Captcha validation failed, handle accordingly
    echo "Captcha validation failed";
}
