In this video, I have explained Google reCAPTCHA V2 Server-Side Verification using PHP step by step.

A few years ago, I uploaded a video on how to integrate Google reCAPTCHA in a form. Many viewers commented that reCAPTCHA was not working properly and that the form was submitting even without clicking on the captcha. The main reason behind this issue is missing server-side verification.

Relying only on client-side protection leaves your website vulnerable to automated bots and spam submissions. Learn the correct, professional way to safely validate the reCAPTCHA response token on your server using PHP, ensuring your forms are truly secure.
