Free Udemy Course 2025: PHP for Beginners: The Complete PHP Intermediate Course 2026

Are you ready to take your PHP skills to the next level and start building professional, scalable web applications?Welcome to the Intermediate PHP Course — a hands-on, project-based journey designed to bridge the gap between beginner and advanced PHP development.In this course, you’ll move beyond the basics of syntax and simple scripts to learn how to structure, secure, and scale your PHP applications using modern techniques and best practices. You’ll gain the confidence and clarity needed to write production-ready code and understand how real-world PHP projects are built.We’ll begin with a quick setup and introduction to ensure your environment is ready (PHP, MySQL, and VS Code). Then we’ll dive deep into Object-Oriented Programming (OOP) — the foundation of modern PHP. You’ll learn about classes, inheritance, interfaces, traits, and magic methods, and how to use namespaces to organize your code efficiently.Next, you’ll master working with files and directories, including file uploads, permissions, and security best practices. From there, we’ll explore how to work with databases using PDO, including prepared statements, transactions, and error handling. You’ll solidify these skills through a mini-project — building a task manager or notes app with full CRUD functionality.Security is a core focus of this course. You’ll learn to protect your applications against common attacks like XSS, CSRF, and SQL Injection, while also understanding proper password hashing, session handling, and secure cookies.Then, you’ll move on to building and consuming APIs, learning the fundamentals of RESTful design, request routing, responses, HTTP methods, response codes, and JSON data formats. Then you’ll move step-by-step through building a fully functional REST API using pure PHP — with clean code organization, routing, error handling, and security best practices. You’ll learn how to connect your API to a MySQL database using PDO, work with CRUD operations, and return structured JSON responses. Finally, we’ll wrap up with an introduction to frameworks, where you’ll learn how frameworks like Laravel implement MVC, routing, controllers, and views. You’ll even learn how to migrate a raw PHP app into Laravel to see the difference in structure and workflow.By the end of this course, you’ll have the skills, mindset, and portfolio projects needed to confidently move into modern PHP development — whether your goal is to freelance, get hired, or start building your own SaaS apps.
