Are there any PHP libraries or tools recommended for testing website security against Spambots?

Spambots are automated programs designed to submit spam content on websites, often through forms or comment sections. To test website security against Spambots, it is recommended to use tools or libraries that can detect and prevent spam submissions. One popular tool for this purpose is Google reCAPTCHA, which provides a CAPTCHA system to verify that the user is human and not a bot. 

// Example code using Google reCAPTCHA to prevent spam submissions

// Include the reCAPTCHA PHP library
require_once('recaptchalib.php');

// Set your reCAPTCHA site key and secret key
$siteKey = 'YOUR_SITE_KEY';
$secret = 'YOUR_SECRET_KEY';

// Verify the reCAPTCHA response
$recaptcha = new ReCaptcha($secret);
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);

if ($resp->isSuccess()) {
    // Process the form submission
    // This is a human user
} else {
    // Display an error message
    echo 'reCAPTCHA verification failed. Please try again.';
}
