03Web PHPBuild server-side web pages, forms, sessions, uploads, and routing in PHP.

04First PHP ProjectsApply the fundamentals in small projects before moving into larger application concerns.

05Databases Storage And CachingStore, retrieve, cache, and test application data with PHP.

06Code Quality And ToolingBuild cleaner code with formatting, debugging, testing, and review habits.

Collaboration And Architecture

27Engineering Collaboration PracticesUse XP, pairing, mob programming, code review, and delivery-flow practices to improve feedback, shared ownership, and team learning.

19Git And Collaboration WorkflowsUse Git safely from local commits through reviewed, automated, and coordinated delivery.

22GitHub And Open Source CollaborationUse GitHub for trustworthy repositories, identity, access, reviews, automation, and open-source collaboration.

07Composer And EcosystemUse Composer, packages, standards, and framework ecosystems with confidence.

08Objects Namespaces And Application ArchitectureOrganize PHP code with objects, namespaces, and application structure.

29Design Patterns And Data ArchitectureUse MVC, front controllers, factories, repositories, and database architecture patterns deliberately in PHP applications.

Application Systems

26PHP Mechanics And ReflectionClarify PHP access syntax, dynamic keys and properties, constructor shorthand, property promotion, and reflection for framework and tooling work.

20Algorithms And Data StructuresChoose practical data structures and algorithms for reliable, measurable PHP applications.

09SecurityLearn the security habits needed to protect PHP applications.

24Authentication And Identity SystemsDesign PHP login and identity systems with passwords, OAuth/OIDC, tokens, magic links, SMS, passkeys, sessions, recovery, and threat modeling.

10HTTP Clients And APIsCall APIs, handle HTTP responses, and build reliable integrations from PHP.

31GraphQLLearn GraphQL end to end: the type system, queries, mutations, subscriptions, validation and execution, serving over HTTP with PHP, plus authorization, pagination, caching, error handling, schema governance, and federation.

21Concurrency Race Conditions And State CoordinationKeep browser, PHP, database, cache, queue, and external-service state correct when work overlaps.

11Testing PHP ApplicationsTest PHP applications with practical unit, integration, and workflow tests.

Production And Reference

12PHP Runtime And Server EnvironmentUnderstand how PHP runs locally, on servers, and in production environments.

25Scheduling And Background WorkRun scheduled PHP work safely with cron, request-triggered scheduling, locks, leases, idempotency, distributed coordination, and missed-run monitoring.

13Deployment And OperationsDeploy, monitor, and operate PHP applications after they go live.

30VercelLearn how to deploy modern frontend and full-stack web apps with Vercel, including Git-based deployments, preview environments, production domains, environment variables, serverless functions, routing config, analytics, storage options, and safe cost/security practices.

23Production Security And Server HardeningHarden production servers, services, access, updates, monitoring, and incident-ready operating baselines.

28Observability Monitoring And Incident ResponseMonitor PHP applications and infrastructure with logs, metrics, traces, health checks, error tracking, deployment verification, alerting, and runbooks.

14Advanced PHP LanguageGo deeper into PHP features used in larger and more modern codebases.

15PHP Version GuideUnderstand PHP version changes and modernize older code safely.

16Practical Capstone ProjectsCombine earlier skills in larger projects that resemble maintainable PHP applications.

17Exercises And SolutionsPractice the course material with exercises, hints, and worked solutions.

18Reference AppendicesFind quick references for PHP syntax, functions, configuration, and conventions.
