The `Io\Poll` API provides an object-oriented interface for monitoring multiple sockets, pipes, or files for I/O readiness, replacing the cumbersome `stream_select()` approach. The polyfill uses a portable Poll backend without edge-triggered event support; on PHP 8.6+, the native implementation takes over automatically with optimized backends like epoll, kqueue, or WSAPoll. The release also includes compatibility fixes for Grapheme, Intl, and PHP version polyfills. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I use PHP 8.6's Io\Poll API if my application still runs on PHP 8.1? Install the symfony/polyfill-io-poll package via composer require symfony/polyfill-io-poll, which ships in Symfony Polyfill 1.41.0. It provides the same Context, Event, and Watcher classes as PHP 8.6's native Io\Poll API, using a portable Poll backend, though it does not support edge-triggered events like the native implementation does. _daily.dev helps developers track PHP polyfill releases before rolling out new async I/O code._ ### What is the Io\Poll API introduced in PHP 8.6? Io\Poll is a new object-oriented API in PHP 8.6 for waiting on multiple I/O resources, such as sockets, pipes, or files, to become ready for read, write, error, or hang-up events. It replaces manual use of stream_select() and parallel arrays, and on PHP 8.6+ it can automatically select optimized platform backends like epoll, kqueue, or WSAPoll. _Developers evaluating PHP's new async I/O primitives can follow updates like this on daily.dev._ ## Similar posts on daily.dev - [Symfony Polyfill 1.34.0 released \(Symfony Blog\)](https://daily.dev/posts/symfony-polyfill-1-34-0-released-symfony-blog--zcggzjfly) · Symfony · 7 upvotes · 0 comments - [What's new in PHP 8.6](https://daily.dev/posts/what-s-new-in-php-8-6-eixar55ou) · stitcher.io · 103 upvotes · 7 comments - [Symfony 7.4.1 released \(Symfony Blog\)](https://daily.dev/posts/symfony-7-4-1-released-symfony-blog--37obpycqi) · Symfony · 1 upvotes · 1 comments --- Tags: [#php](https://daily.dev/tags/php), [#symfony](https://daily.dev/tags/symfony) [View this post on daily.dev](https://daily.dev/posts/symfony-polyfill-1-41-0-released-io-poll-now-available-symfony-blog--t676gb2ts) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Symfony Polyfill 1.41.0 released: Io\\Poll now available (Symfony Blog)","url":"https://daily.dev/posts/symfony-polyfill-1-41-0-released-io-poll-now-available-symfony-blog--t676gb2ts","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/symfony-polyfill-1-41-0-released-io-poll-now-available-symfony-blog--t676gb2ts"},"datePublished":"2026-08-03T14:31:11.768Z","dateModified":"2026-09-14T06:52:27.714Z","description":"Symfony Polyfill 1.41.0 introduces a new `symfony/polyfill-io-poll` package that backports PHP 8.6's `Io\\Poll` API to PHP 8.1 and later.
