PHP Traits, Threat or Treat?
summary
Claims concrete results: PHP 5.4 cuts CPU from 600ms to 168ms and memory from ~14MB to ~8MB in a cloned VM benchmark using XHProf, and traits offer reuse by being copy‑pasted into classes at compile time, with clear rules for conflicts via insteadof and renaming so you can implement interfaces by aliasing methods. Gotchas: static properties behave per‑class, no instanceof for traits, and method renames complicate refactoring.
