This is your battle plan. Stick to it, and you will emerge a PHP master.

1. What to learn: Dive deep into PHP's basic syntax, data types (scalar, compound, special), variables, operators, control structures (if/else, switch, loops), functions (declaration, parameters, return types, anonymous functions, arrow functions), and basic error handling with E_NOTICE, E_WARNING, E_ERROR. Understand type juggling vs. strict types (declare(strict_types=1);). Explore PHP's execution model and the request/response lifecycle.

   Why this comes before the next step: Without a rock-solid understanding of these fundamentals, everything else you build will be shaky. You need to speak the language fluently before you can write poetry. This forms the bedrock upon which all advanced concepts are built.

   Mini-project/Exercise: Write a CLI script that takes command-line arguments, performs various calculations based on user input, and outputs formatted results. Implement basic error checking for invalid input types and ranges, using strict types.

2. What to learn: Master classes, objects, properties, methods, constructors, destructors, visibility (public, protected, private). Grasp inheritance, abstract classes, interfaces, traits, and polymorphism. Understand static properties/methods, constants, and the self, static, and parent keywords. Explore basic design patterns like Singleton and Factory (as conceptual tools, not dogma).

   Why this comes before the next step: Modern PHP development is inherently object-oriented. You cannot effectively use Composer, frameworks, or even many SPL components without a deep grasp of OOP. This week equips you to organize complex codebases logically.

   Mini-project/Exercise: Build a simple "shape calculator" library. Create an abstract Shape class with methods like getArea() and getPerimeter(). Implement concrete classes like Circle, Rectangle, and Triangle that extend Shape and implement an InfoProvider interface. Use traits for common functionality (e.g., Timestampable).

3. What to learn: Understand Composer: what it is, how to initialize a project (composer init), manage dependencies (composer require, composer update), and generate an autoloader. Deep dive into PSR-4 autoloading: how it maps namespaces to file paths. Explore other crucial PSRs like PSR-1 (Basic Coding Standard), PSR-2 (Coding Style Guide - now superseded by PSR-12), PSR-3 (Logger Interface), and PSR-7 (HTTP Message Interface - conceptual understanding). Learn to create your own Composer package.

   Why this comes before the next step: Composer and PSRs are the backbone of modern PHP interoperability and project structure. You cannot effectively integrate libraries or build scalable applications without understanding these standards. This week makes your code professional and shareable.

   Mini-project/Exercise: Create two separate Composer packages: one containing your "shape calculator" library from Week 2, and another "CLI application" package. The CLI app should require your shape calculator via Composer and use its classes via PSR-4 autoloading to perform calculations based on user input.

4. What to learn: Master PHP's robust exception handling mechanism (try...catch...finally, custom exceptions). Understand the difference between errors and exceptions and how to convert errors to exceptions. Explore the Standard PHP Library (SPL): iterators, data structures (SplQueue, SplStack, SplFixedArray), and file system functions. Learn about error reporting levels and custom error handlers.

   Mini-project/Exercise: Build a "log processing" CLI tool. It should read a large log file line by line (using SPL iterators), parse each line, and categorize errors. Implement custom exceptions for different types of parsing failures or log levels. Use an SPL data structure (e.g., SplQueue) to temporarily store critical error messages before writing them to a separate error log file.

5. What to learn: Dive into PHP 8+ features: Attributes, Enums, Union Types, Constructor Property Promotion, Match Expressions, Nullsafe Operator, and Named Arguments. Understand JIT (Just-In-Time) compilation and its implications. Explore Fibers for cooperative multitasking. Reinforce type declarations and strict typing. Discuss immutability, value objects, and defensive programming.

   Why this comes before the next step: PHP is constantly evolving. Staying current with modern features allows you to write more expressive, safer, and often more performant code. This week brings your knowledge to the cutting edge, making you ready for real-world application building.

   Mini-project/Exercise: Refactor your "log processing" tool or the "shape calculator" to extensively use modern PHP features. Implement Enums for log levels or shape types. Use Attributes to define metadata for your classes or methods (e.g., a #[Loggable] attribute). Experiment with Fibers to simulate processing multiple log streams concurrently (cooperatively).

6. What to learn: Understand PHP's interaction with web servers (Apache/Nginx), environment variables, $_GET, $_POST, $_SERVER, $_SESSION, $_COOKIE. Learn about basic routing. Deep dive into security: SQL injection prevention (PDO prepared statements), XSS prevention (htmlspecialchars), CSRF tokens (conceptual), password hashing (password_hash). Explore performance considerations: opcode caching (OPcache), profiling (Xdebug - conceptual), memory management, and database query optimization basics.

   Why this comes before the next step: You now have a deep language understanding. This week bridges that knowledge to building secure, performant web applications, preparing you for real-world deployment and framework integration with a critical eye.

   Mini-project/Exercise: Build a simple, secure "guestbook" web application from scratch (no framework). It should have a single page to display entries and a form to submit new ones. Implement full security measures: use PDO with prepared statements for database interaction, htmlspecialchars for all user output, and password_hash if you add user authentication. Deploy it using PHP's built-in web server or a local Apache/Nginx setup.
