Short lessons, an editor that runs your code and shows the result as a real web page, 60 coding missions and an AI mentor that explains your errors. A PHP COURSE FROM BEGINNER TO BACKEND 49 courses and 195 lessons, ordered from level A1 to C2, so a complete beginner and a working developer both find the next step: • Basics: variables, types, echo, control flow, loops, functions and scope • Arrays and array functions, string functions, date and time • HTML pages: embedding code in a page, GET and POST forms, sessions and cookies • Object-oriented programming (OOP): classes, inheritance, interfaces, traits, namespaces, PSR-4 autoloading and Composer • MySQL with PDO and prepared statements, JSON and consuming REST APIs • PHP 8.x features, error handling, exceptions and regular expressions • Laravel: MVC and routing, Eloquent ORM, authentication, queues and building REST APIs • Security (XSS, CSRF, SQL injection), unit testing with PHPUnit, deployment • Advanced: Symfony components, Redis caching, design patterns and SOLID, Docker and CI/CD, microservices WRITE AND RUN CODE • A mobile IDE with a code editor and compiler: write a script, tap Run, see the output (running code needs an internet connection) • Page view: when your script prints HTML, you see it rendered as a web page, next to the source and the console • Request simulator: fill in $_GET, $_POST, cookies and the session, then run your script as if a browser sent the request • Database sandbox: practise PDO against a real SQLite database with tables you can query • Error messages point to the line in your own code, and you can ask the AI mentor what went wrong PRACTICE THAT FEELS LIKE REAL WORK • 60 coding missions: 20 easy, 20 medium, 20 hard, from FizzBuzz to recursion, usort and a class of your own • Build a web app step by step: a contact form, a login system, a blog with CRUD and a REST API, 8 steps each • 20 guided projects with starter code and hints • Bug Hunt: fix a broken script every day before you run out of lives • Function of the Day: short recall drills that bring built-in functions back just before you forget them • Framework taster: practise Laravel and Symfony patterns such as routes, views and a query builder on a small teaching framework (clearly labelled as not the real framework) GET READY FOR A BACKEND JOB • 50 interview questions with clear answers • 50 quiz questions to check what stuck • A cheat sheet with 71 entries, from strict types to PDO • A final exam and a certificate of completion (Pro) AI MENTOR Ask about any concept, error message or piece of code and get a clear explanation in seconds.
