PHP Security Essentials for Web Developers

Building web applications with PHP is an essential skill, but ensuring those applications are safe from malicious attacks is what defines a professional developer. Protecting user data is a critical responsibility that requires a proactive approach to coding and system design. You will transition from writing functional code to writing secure code by understanding how attackers exploit vulnerabilities and how to block them using modern PHP features. This course provides the foundational knowledge needed to identify risks and implement robust defenses in your projects. What you'll learn: - Understand the most common web security risks and how they impact PHP applications - Apply prepared statements using PDO to eliminate SQL injection risks - Implement robust input validation and output encoding to prevent Cross-Site Scripting (XSS) - Master modern password security using current hashing algorithms and secure storage - Configure secure session handling and protect against Cross-Site Request Forgery (CSRF) - Practice defensive coding patterns to secure file uploads and sensitive data handling The course begins with foundational security terminology and core concepts before moving into detailed text-based walkthroughs of common exploits and their modern programmatic solutions. You will read through clear explanations and code snippets that demonstrate both the vulnerability and the secure fix. This course is designed for beginner PHP developers who want to prioritize security in their development workflow. No prior experience with web security is required, though basic familiarity with PHP syntax is helpful. Enhance your development skills by learning to build resilient and secure PHP applications.
