Short summary

Generators reduce memory from 462MB to 0.3MB and speed up processing 2.4× using yield; Named Arguments skip optional params and self-document code; Fibers enable cooperative multitasking for async frameworks. Real benchmarks and code examples demonstrate each pattern. Immediately applicable for PHP 8.1+.

• •Generators use yield to stream large datasets with minimal memory (462MB → 0.3MB on 1M rows, 2.4× faster)
• •Named Arguments improve readability, skip optional parameters, and enable cleaner dependency injection via spread
• •Fibers provide cooperative multitasking primitive that powers async frameworks like ReactPHP and Swoole
