PHP / Advanced: reliable models and runtime evidence

PHP โ€” Advanced: reliable models and runtime evidence

Apply advanced types, resource ownership, security, performance, APIs, and version compatibility.

6 lessons ยท No account required

What you will learn

  • State runtime and analyzer boundaries honestly.
  • Maintain explicit APIs and evidence-based release decisions.

  1. Advanced types and explicit domain models

    Use union, intersection, enum, and readonly features within declared version boundaries. Explain what PHP checks natively and what documentation or static analysis adds without inventing native generics.

  2. Generators, streams, and resource lifetime

    Consume bounded data incrementally and pair resource acquisition with release. Distinguish a lazy sequence from a reusable collection and validate stream behavior using owned memory only.

  3. Security boundaries and sensitive operations

    Connect validation, SQL binding, output handling, session policy, and authorization without calling one defense a universal sanitizer. Use only synthetic local examples and safe password verification.

  4. Performance, allocation, and runtime evidence

    Improve a correct PHP workload using measured hypotheses and bounded data. Distinguish algorithm choices, request lifecycle, OPcache, JIT, and database cost without universal tuning prescriptions.

  5. Maintainable HTTP and JSON API boundaries

    Compose parsing, authorization, domain work, persistence, and response construction without a framework. Use explicit adapters and error contracts instead of coupling business rules to superglobals.

  6. Runtime versions, feature boundaries, and compatibility

    Read support schedules and migration guides as maintained evidence. Compare labeled PHP 8.4 and 8.5 features without silently raising the courseโ€™s PHP 8.3 syntax baseline.
