Symfony Polyfill / Io / Poll
============================

[](#symfony-polyfill--io--poll)

This component provides the [`Io\Poll` API](https://wiki.php.net/rfc/poll_api)added to PHP 8.6 core, for PHP >= 8.1:

- `Io\Poll\Context`, `Io\Poll\Watcher` and `StreamPollHandle`
- `Io\Poll\Backend` and `Io\Poll\Event` enums
- `Io\IoException` and the `Io\Poll\*Exception` hierarchy

The polyfill is backed by `stream_select()`, so only the `Poll` backend is available and edge-triggering is not supported. Event detection follows the semantics of the native `poll` backend as closely as `select()` allows: `Event::Error` is only reported for connection resets, `Event::ReadHangUp` is never reported, and a TCP half-close reports `Read|HangUp` where native reports plain `Read`. The phpt tests of the native implementation, borrowed from php-src, run against the polyfill as part of the test suite.

More information can be found in the [main Polyfill README](https://github.com/symfony/polyfill/blob/main/README.md).
