PHP OOP: Database Integration with PDO

Database-driven applications are the backbone of the modern web, but writing insecure, procedural database code can lead to critical vulnerabilities and maintenance nightmares. This text-only course guides you from PHP database basics to building secure, object-oriented database layers using PHP Data Objects (PDO). You will learn how to transition away from outdated database extension methods and adopt industry-standard practices that keep your web applications safe and organized. What you'll learn: - Learn the core concepts of Object-Oriented Programming (OOP) in PHP, including classes, objects, and modern constructor promotion. - Configure secure database connections using PDO and handle connection errors gracefully using exceptions. - Prevent SQL injection vulnerabilities by mastering prepared statements and parameterized queries. - Implement complete CRUD (Create, Read, Update, Delete) operations wrapped in reusable PHP classes. - Apply modern PHP practices such as type hinting, strict types, and basic dependency injection. - Structure your database logic using clean design patterns for more maintainable codebases. The course begins with essential database and OOP terminology before moving step-by-step through connection management, secure querying, and building a modular database class. Perfect for beginner PHP developers who want to transition from procedural coding to professional, object-oriented database programming, this course requires no advanced PHP experience.
