Description

Security is one of the most critical aspects of web development — yet it is often overlooked by beginners when learning PHP. The truth is, even a small mistake in your code can open the door for attackers to steal sensitive data, compromise user accounts, or take full control of your application. That’s why I created this course: PHP for Beginners: The Complete PHP Security Course 2025.This course is designed to give you a step-by-step guide to securing your PHP applications, even if you are just starting out. You’ll not only learn how hackers exploit insecure PHP code, but also how to defend against real-world attacks. We’ll cover everything from SQL Injection and Cross-Site Request Forgery (CSRF), to session fixation, secure file uploads, and safe error handling.Through practical examples, I’ll show you exactly how these attacks work and how to fix them. You’ll practice using prepared statements to secure your database queries, hashing and verifying passwords with PHP’s modern password functions, and configuring PHP for a production environment. You’ll also learn how to protect your application at the server level using .htaccess rules, directory restrictions, IP-based protection, and HTTPS enforcement.By the end of this course, you will have the knowledge and confidence to write PHP code that is not only functional, but also secure and production-ready. Whether you are building your first web project, working on an eCommerce site, or managing client applications, the skills you learn here will help you protect both your users and your reputation.If you’re serious about becoming a PHP developer in 2025, security is no longer optional — it’s a must. Enroll today and take the first step toward building safe, professional, and secure PHP applications.
