Contact Form process in PHP with google reCAPTCHA validation

Contact Form process in PHP with google captcha validation.

Protect your website from spam and abuse while letting real people pass through with ease.

The new reCAPTCHA is here. A significant number of your users can now attest they are human without having to solve a CAPTCHA. Instead with just a single click they’ll confirm they are not a robot. We’re calling it the No CAPTCHA reCAPTCHA experience.
