PHP & MySQL Tutorial¶
Recommended order: PHP roadmap -> Foundations -> Control Flow -> Functions -> MySQL -> CRUD -> Projects
Best for: Beginners, BCA/MCA students, web development aspirants
Prerequisites: Basic HTML knowledge helpful
PHP powers over 75% of all websites on the internet — including WordPress, Facebook (historically), and Wikipedia. Paired with MySQL, it lets you build fully dynamic, database-driven web applications. This roadmap takes you from your first echo to a complete CRUD application.
