The phasync framework is a new coroutine library for PHP which works without any extensions. With phasync, you can use asynchronous IO operations while writing code the way you have always done it in PHP.
Whenever you need to write code that uses coroutines, you simply use phasync::run(). You can use it in your existing codebase without changing anything else.
class SomeController {
public function someMethod(): string {
// Create a context for using async code
return phasync::run(function() {
// Write your code here
$client = new HttpClient();
// Another coroutine just for fun
$result = phasync::go(function() {
for ($i = 0; $i < 10; $i++) {
echo "Counting: $i\n";
phasync::sleep(0.5);
}
return $i;
});
// These requests run in parallel
$request1 = $client->get("http://example.com/");
$request2 = $client->get("http://example2.com/");
return [
$request1,
$request2,
phasync::await($result)
];
});
}
}
