The Complete PHP Course
A practical, modern PHP curriculum: start with your first script, then master web requests, databases, object-oriented design, testing, security, Laravel, architecture, and production deployment.
Phase 1 · PHP Foundations
Setup, syntax, types, strings, arrays, control flow, loops, and functions.
How PHP Powers the Web
Understand PHP's role on the server, set up a modern environment, and run your first web and command-line scripts.
Variables, Types & Constants
Store program data confidently with PHP's variables, core types, conversions, constants, and essential debugging tools.
Operators, Expressions & Strings
Calculate, compare, combine, and format values while avoiding PHP's most common comparison and string pitfalls.
Arrays & Data Collections
Model lists and records with PHP arrays, then sort, filter, map, reduce, destructure, and safely inspect them.
Decisions & Control Flow
Make programs choose the right path with clear conditions, guard clauses, match expressions, and safe comparisons.
Loops & Iteration
Repeat work with while, for, and foreach, traverse real data, and choose between loops and array functions.
Functions & a CLI Mini Project
Design reusable typed functions, work with scope and closures, and combine Phase 1 skills in an expense-summary project.
Phase 2 · Web Fundamentals
HTTP, forms, validation, sessions, files, authentication, and templates.
HTTP & the PHP Request Lifecycle
Trace a request from browser to server and build correct PHP responses with headers and status codes.
Forms, GET & POST
Build accessible forms and process query strings and request bodies without mixing responsibilities.
Validation, Sanitization & Escaping
Treat browser input as untrusted and apply the right validation, normalization, and output escaping at each boundary.
Superglobals & Application State
Use PHP's request data, cookies, and sessions to carry intentional state across stateless HTTP requests.
Files, Uploads & Downloads
Read and write files, persist JSON and CSV, and handle uploads and downloads with strict safety checks.
Authentication Foundations
Create safe registration, login, logout, authorization, password, session, and CSRF flows.
Templates, Layouts & Reusable Views
Compose maintainable server-rendered interfaces from escaped views, layouts, and partials.
Phase 3 · Object-Oriented & Modern PHP
Classes, interfaces, Composer, exceptions, modern types, and design patterns.
Classes, Objects & Encapsulation
Model behavior and invariants with classes, typed properties, constructors, visibility, and immutable value objects.
Inheritance, Interfaces & Traits
Create flexible contracts with interfaces and composition while using inheritance and traits deliberately.
Namespaces, Autoloading & Composer
Organize professional projects with namespaces, PSR-4 autoloading, Composer packages, and reproducible dependencies.
Exceptions & Reliable Error Handling
Design explicit failure paths with Throwable, custom exceptions, cleanup, global handlers, and secure logging.
Modern Types, Enums & Attributes
Use strict types, rich type declarations, enums, attributes, and variance to make illegal states harder to represent.
Closures, Iterators & Generators
Pass behavior as data and stream large sequences lazily with callables, iterators, and generators.
SOLID & Essential Design Patterns
Improve changeability with SOLID, dependency injection, and a small set of patterns applied only where they earn their keep.
Phase 4 · Databases & Persistence
SQL, PDO, CRUD, modeling, migrations, security, and a data-driven project.
Relational Databases, SQL & PDO
Learn relational foundations and execute safe, parameterized SQL through PDO.
CRUD, Transactions & Error Handling
Build complete persistence workflows and protect multi-step changes with atomic transactions.
Data Modeling & Joins
Design normalized relationships and query them efficiently with joins, constraints, and indexes.
Migrations, Repositories & Data Mappers
Version schemas and isolate persistence behind testable repositories and mapping boundaries.
Database Security & Performance
Harden database access and diagnose slow workloads with least privilege, indexes, profiling, and recovery planning.
Project: Data-Driven Content App
Combine authentication, CRUD, validation, search, pagination, transactions, tests, and security in one application.
Phase 5 · Professional Applications
MVC, REST APIs, configuration, testing, quality, security, caches, and queues.
Routing, Controllers & MVC
Build a small framework-style architecture with routing, middleware, controllers, services, views, and dependency injection.
REST APIs & JSON
Design predictable JSON APIs with resource URLs, correct HTTP semantics, validation, errors, and documentation.
Configuration, Environments & Packages
Bootstrap applications with environment-aware configuration, protected secrets, and disciplined dependency management.
Automated Testing with PHPUnit
Write fast unit tests, meaningful integration tests, and reliable feature tests with PHPUnit.
Static Analysis, Style & Refactoring
Use standards, formatters, static analysis, automated upgrades, and quality gates to improve code safely.
Web Application Security
Threat-model a PHP application and defend its most important input, identity, authorization, browser, and dependency boundaries.
Cache, Queues & Background Work
Improve responsiveness and resilience with caches, background jobs, retries, idempotency, scheduling, and email.
Phase 6 · Laravel Mastery
Build, test, secure, optimize, and deploy full Laravel applications.
Laravel Fundamentals
Navigate Laravel's lifecycle, structure, routing, controllers, middleware, views, service container, and configuration.
Eloquent, Migrations & Validation
Model, validate, query, relate, seed, and paginate application data with Laravel's database tools.
Authentication & APIs in Laravel
Implement identity, policies, token-secured APIs, resources, rate limits, and safe account workflows.
Jobs, Events, Notifications & Caching
Build responsive Laravel systems with workers, events, notifications, cache locks, and the scheduler.
Testing & Deploying Laravel
Test HTTP and database behavior, use fakes effectively, optimize production builds, and plan zero-downtime releases.
Phase 7 · Advanced & Portfolio
Performance, architecture, containers, CI/CD, observability, CMS work, and capstones.
Performance & PHP Runtime Internals
Understand PHP execution, OPcache, memory, profiling, load tests, and the real bottlenecks in web applications.
Architecture for Growing Systems
Shape maintainable boundaries with modular monoliths, clean architecture, DDD building blocks, and deliberate distributed systems.
Containers, CI/CD & Observability
Containerize PHP, automate quality and releases, and operate applications with logs, metrics, traces, and health checks.
CMS & WordPress Development
Apply professional PHP practices to themes, plugins, hooks, data APIs, security, and maintainable CMS extensions.
Portfolio Capstones
Prove the full learning path through progressively larger CLI, web, API, Laravel, and production architecture projects.
