Implement concurrency and non-blocking I/O in modern PHP. An agent skill from HoangNguyen0403/agent-skills-standard.

  • Implementing concurrent requests
  • SKILL.md covers Priority: P2 (MEDIUM), Structure, Implement PHP Fibers (8.1+) and Configure Non-blocking I/O &…, plus 5 more sections

What it does

Php Concurrency is an agent skill from HoangNguyen0403/agent-skills-standard. Implement concurrency and non-blocking I/O in modern PHP. Use when implementing concurrent requests, async processing, or non-blocking I/O in PHP.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Development, covering Async programming. It works with PHP. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Implementing concurrent requests
  • Async processing
  • Non-blocking I/O in PHP

Example prompts

  • “/php-concurrency”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Php Concurrency loads about 683 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 260 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~683
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PHP Concurrency

Priority: P2 (MEDIUM)

Structure

See implementation examples for directory layout.

Implement PHP Fibers (8.1+)

  • Multitasking: Use new Fiber() for low-level cooperative multitasking.
  • Yielding Control: Use Fiber::suspend('paused') to yield execution back to caller.
  • Resuming: Call $fiber->resume('hello') to continue execution. Catch exceptions via $fiber->getReturn().
  • Isolation: Use separate PDO connections per Fiber to avoid shared mutable state.

See implementation examples for Fiber cooperative multitasking code.

Configure Non-blocking I/O & Event Loops

  • Loop Setup: Use ReactPHP or Amp. Call Loop::get() to access event loop.
  • HTTP Clients: Use react/http or Guzzle Pool($client, ...) for concurrent requests.
  • I/O Safety: Never use blocking file_get_contents or sleep() inside Fiber or EventLoop.
  • Entry Point: Run Loop::run() at your application entry point to start async loop.

See implementation examples for concurrent HTTP requests with Guzzle Pool.

Choose Concurrency Strategies

  • Queued Jobs: For heavy concurrency, prefer Laravel Horizon or Symfony Messenger over raw PHP Fibers.
  • Self-Contained Logic: Ensure Fibers manage their own state and exceptions to prevent cross-contamination.

Anti-Patterns

  • No deeply nested Fiber suspends: Keep Fiber logic traceable.
  • No blocking I/O inside Fibers: Use async-compatible libraries.
  • No custom scheduler code: Use Amp or ReactPHP instead.

References

Isolation checklist

  • Do not share mutable connection state across Fibers; use a separate PDO connection per Fiber or enforce bounded concurrency with queued work.

Canonical response anchors

When this skill applies, preserve the following domain terminology or equivalent concrete examples in the answer when relevant:

  • Do not share mutable,connection state,Bound concurrency

  • Use Guzzle pool for concurrent requests,guzzle

  • Pool($client

  • do not call blocking file_get_contents,non-blocking I/O

  • Additional task-grounded exact anchors: Loop::get(); separate PDO connection
