In PHP 8.1, Fiber::suspend() yields control to the caller and the value passed to resume() becomes the return value of the suspend call: ~~~php $fiber = new Fiber(function (): string { $input = Fiber::suspend('paused'); return 'received ' . $input; }); $fiber->start(); $fiber->resume('hello'); $output = $fiber->getReturn(); ~~~ Resume only a started, suspended Fiber and handle exceptions at the boundary.
