Secure PHP Programming: Defend Applications Against Exploits

Security is a critical pillar of web development, yet many PHP applications remain vulnerable to preventable exploits. Learn how to transform your coding habits to build resilient, secure web applications from the ground up. This text-based course guides you through the core principles of secure PHP development. You will learn to identify common vulnerabilities, implement robust defense mechanisms, and adopt modern security best practices to protect user data and application integrity. What you'll learn: - Understand foundational web security concepts and the common exploit landscape. - Filter, validate, and sanitize user input to prevent malicious data entry. - Prevent SQL injection using modern PDO and prepared statements. - Defend against Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). - Secure file uploads and manage user sessions safely. - Apply modern PHP password hashing techniques and secure environment configuration. The course begins with essential security terminology and foundational concepts before moving into practical code-level defenses. You will progress from basic input validation to advanced database security and session management through detailed written explanations and code analysis. This course is designed for PHP developers who want to transition from writing functional code to writing secure, production-ready applications. No prior security experience is required.
