1. Prioritizing Technical Debt in PHP Projects

   Feb 19, 2025

   Every grown PHP project accumulates technical debt, the question is never whether but which item should be fixed first. This article shows a practical method for scoring technical debt by change frequency, risk of failure and fix effort, and deriving a defensible order from it.

2. Asymmetric Visibility in PHP 8.4: public get, private set

   Feb 18, 2025

   For years, developers reached for a private property plus a public getter just to allow read access from the outside, without opening up write access. Asymmetric Visibility ends that detour: a property can be publicly readable and privately or protected writable at the same time, directly in the declaration, without a single line of getter code.

3. API Authentication in PHP: Using API Keys, JWT and OAuth2 Correctly

   Feb 17, 2025

   Choosing the right authentication mechanism decides the security and integration effort of a PHP API. This article shows when API keys are enough, how JWT signatures really work, and when the extra effort of OAuth2 truly pays off, with secure storage and full code examples.

4. Traits vs. Interfaces: Cleanly Separating Code Reuse

   Feb 15, 2025

   A trait copies real method bodies straight into a class, an interface only promises those methods exist, without shipping a single line of implementation. Anyone who mixes traits and interfaces, or swaps one for the other, loses exactly the sharpness that makes object-oriented design robust: horizontal reuse of behavior on one side, binding contracts for polymorphism and testability on the other.

5. Understanding Copy-on-Write in PHP Arrays

   Feb 11, 2025

   An assignment like $b = $a for a large PHP array looks at first glance like an expensive copy operation, but internally it initially only costs incrementing a reference counter. Copy-on-Write postpones the actual copy to the moment one of the two variables is actually modified, and this exact mechanism decides memory usage and performance for every array hand off in PHP.

6. Test Doubles and Mocking Strategies: Dummy, Stub, Fake, Spy, Mock

   Feb 10, 2025

   Mocking everything a class touches, indiscriminately, produces unit tests that break on every refactor even though the application's behavior never changed. Gerard Meszaros' taxonomy distinguishes dummy, stub, fake, spy and mock as five clearly separated roles, each with a different purpose, a different verification logic and a different degree of coupling to implementation details. This article walks through the theory behind every test double using hand-written PHP implementations, independent of any particular testing framework.

7. Managing a PHP Monorepo with Multiple Packages: Composer Path Repositories

   Feb 7, 2025

   Anyone maintaining several related PHP packages knows the pain: every small change in the core package means a new version, a new tag, and a composer update in every dependent package just to test locally whether everything still fits together. A PHP monorepo with Composer path repositories solves exactly this problem, without making the later release to Packagist any harder.

8. Build-Time Code Generation in PHP: Generating Boilerplate Instead of Runtime Reflection

   Feb 1, 2025

   Build-time code generation produces finished, compilable PHP code before an application even starts, instead of reading metadata via reflection again on every request. Symfony and Laravel use this technique for compiled containers, because generated code is treated by OPcache like any regular code and reflection overhead disappears entirely from the hot path.

9. Parallel PHP with Swoole Coroutines: The Complete Practical Guide

   Feb 1, 2025

   Swoole Coroutines let PHP handle thousands of concurrent tasks efficiently without spawning threads or extra processes. Once you understand how the cooperative coroutine scheduler works, and how channels and WaitGroup synchronize results, you can use Swoole Coroutines for real concurrency in PHP without inheriting the classic pitfalls of threading.

10. WeakMap and WeakReference in PHP: Building Caches Without Memory Leaks

    Jan 30, 2025

    An ordinary array used as a cache with objects as keys or values prevents those objects from ever being collected by the garbage collector as long as the cache itself exists, and that is exactly what leads to creeping memory leaks in long running processes. WeakMap solves this problem structurally by removing the cache's own influence on the lifetime of the referenced objects.
