Here Is What He Told Me… **[Medium](https://daily.dev/sources/medium_js)** · 6 min read · 0 upvotes · 0 comments ## Summary A PHP-focused rundown of five coding patterns shared by a self-described senior developer: the Yoda pattern for catching accidental assignment typos in conditionals, a Dispatcher pattern to replace bloated switch/if-else chains, early returns to reduce nesting, avoiding mutation of referenced input data, and using constants plus final classes with composition/Decorator pattern instead of inheritance. Ends with a plug for a free companion repo meant to make AI coding assistants like Claude, Cursor, and GitHub Copilot enforce these patterns automatically. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Yoda pattern in PHP and why use it? The Yoda pattern places the fixed value on the left side of a comparison, like `if (5 == $count)`, instead of the variable. If you accidentally type a single equals sign, PHP tries to assign a value to a literal number, which triggers an error immediately instead of silently making the condition always true. _Developers hardening PHP codebases against subtle bugs compare patterns like this on daily.dev._ ### How does the Dispatcher pattern avoid large switch statements when routing to different service classes? A dispatcher class holds a registry of services keyed by type, injected via an addService method, and delegates work by looking up the matching service and calling its method. Instead of adding a new case to a growing switch or if/else block every time a new type appears, you register a new service, keeping the routing class small and testable. _Teams refactoring bloated conditional logic explore alternatives like this on daily.dev._ ## Similar posts on daily.dev - [Design Patterns Suck](https://daily.dev/posts/design-patterns-suck-kei3cx9df) · iamluminousmen · 1 upvotes · 0 comments - [Programming Aphorisms](https://daily.dev/posts/programming-aphorisms-nqlduuooq) · matklad · 4 upvotes · 0 comments - [5 Backend System Design Patterns Every Engineer Should Actually Understand](https://daily.dev/posts/5-backend-system-design-patterns-every-engineer-should-actually-understand-nzc6ercbu) · Medium · 5 upvotes · 0 comments --- Tags: [#php](https://daily.dev/tags/php), [#design-patterns](https://daily.dev/tags/design-patterns) [View this post on daily.dev](https://daily.dev/posts/i-asked-a-senior-developer-for-his-5-best-coding-patterns-here-is-what-he-told-me--xqryvydns) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I Asked a Senior Developer for His 5 Best Coding Patterns.
