Implementation Guidelines

• Fibers: Use Fiber for low-level cooperative multitasking (8.1+).
• Yield Control: Apply Fiber::suspend() to yield within Fibers.
• I/O Bound: Target I/O tasks only; avoid for CPU intensive work.
• Frameworks: Prefer Amp or ReactPHP for complex events.
• Self-Contained: Ensure Fibers manage their own state/exceptions.
• Incremental: Refactor single bottlenecks before full async.

Anti-Patterns

• Implicit Flows: No Deep Suspend: Keep Fiber logic traceable.
• Internal Blocking: No Blocking I/O: Don't block inside Fibers.
• Custom Schedulers: No DIY Schedulers: Use proven async libs.
