In order for async based libraries to be interoperable, they need to use the same event loop. This component provides a common `LoopInterface` that any library can target. This allows them to be used in the same loop, with one single `run` call that is controlled by the user. In addition to the interface there are some implementations provided: - `StreamSelectLoop`: This is the only implementation which works out of the box with PHP. It does a simple `select` system call. It's not the most performant of loops, but still does the job quite well. - `LibEventLoop`: This uses the `libevent` pecl extension. `libevent` itself supports a number of system-specific backends (epoll, kqueue). - `LibEvLoop`: This uses the `libev` pecl extension ([github](https://github.com/m4rw3r/php-libev)). It supports the same backends as libevent. - `ExtEventLoop`: This uses the `event` pecl extension. It supports the same backends as libevent. All of the loops support these features: - File descriptor polling - One-off timers - Periodic timers - Deferred execution of callbacks Usage ----- [](#usage) Here is an async HTTP server built with just the event loop. ``` $loop = React\EventLoop\Factory::create(); $server = stream_socket_server('tcp://127.0.0.1:8080'); stream_set_blocking($server, 0); $loop->addReadStream($server, function ($server) use ($loop) { $conn = stream_socket_accept($server); $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n"; $loop->addWriteStream($conn, function ($conn) use (&$data, $loop) { $written = fwrite($conn, $data); if ($written === strlen($data)) { fclose($conn); $loop->removeStream($conn); } else { $data = substr($data, $written); } }); }); $loop->addPeriodicTimer(5, function () { $memory = memory_get_usage() / 1024; $formatted = number_format($memory, 3).'K'; echo "Current memory usage: {$formatted}\n"; }); $loop->run(); ``` **Note:** The factory is just for convenience. It tries to pick the best available implementation. Libraries `SHOULD` allow the user to inject an instance of the loop. They `MAY` use the factory when the user did not supply a loop. ### Health Score 29 — LowBetter than 57% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity14 Limited adoption so far Community19 Small or concentrated contributor base Maturity56 Maturing project, gaining track record Bus Factor3 3 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
