Contact-Us-Form-with-PHP-Backend-MySQL-Google-reCAPTCHA-Integration-and-Email-Notification

Description:

This Secure Contact Form System is an advanced PHP-based solution designed to provide a secure and robust way for users to send inquiries or messages through a company website. This project includes features such as database integration, server-side validation, sanitization, CSRF protection, and Google reCAPTCHA implementation to ensure data integrity and prevent common security vulnerabilities.

Features:

• Database Integration: Messages submitted through the contact form are securely stored in a MySQL database for future reference.
• Server-side Validation: Basic validation is implemented to ensure that user input meets certain criteria, such as validating email addresses.
• Sanitization: User input is sanitized using htmlspecialchars() to prevent XSS (Cross-Site Scripting) attacks.
• CSRF Protection: CSRF (Cross-Site Request Forgery) tokens are generated and verified to prevent unauthorized form submissions.
• CAPTCHA: Integration with Google reCAPTCHA provides an additional layer of security to prevent automated submissions by bots.
• Responsive Design: The contact form is designed to be responsive and user-friendly across various devices and screen sizes.
• Thank You Page: Upon successful submission, users are redirected to a thank you page to acknowledge their message.
