PHP Form Security: Validation, Password Hashing (Securely Store Data in MariaDB)

In this essential PHP web development tutorial, learn how to build a robust and secure server-side backend for a user registration form.

We go beyond basic client-side checks to implement bulletproof server-side validation using PHP's powerful functions. More importantly, we cover the single most critical step in user security: securely hashing passwords using password_hash() before storage. NEVER store plain-text passwords!

Watch as we connect PHP to a MariaDB database, implement prepared statements (mysqli) to prevent devastating SQL Injection attacks, and set up automatic email notifications for new user registrations. This screencast shows the form submission, the secure database entry, and the admin email delivery in real-time.

What You Will Learn:
- How to implement strict username and password validation in PHP.
- The vital difference between validation and security (hashing).
- Using prepared statements (mysqli) for secure MariaDB/MySQL storage.
- How to send admin email notifications upon successful registration.

Mastering these skills is non-negotiable for any serious web developer. Start building professional, secure applications today!
