Maybe this helps wrapping your had around the start-suspend-resume-return circle:
$fiber = new Fiber(
function($one) {
$two = Fiber::suspend($one);
$three = Fiber::suspend($two);
$four = Fiber::suspend($three);
$five = Fiber::suspend($four);
$six = Fiber::suspend($five);
return $six;
}
);
print $fiber->start(1);
print $fiber->resume(2);
print $fiber->resume(3);
print $fiber->resume(4);
print $fiber->resume(5);
print $fiber->resume(6);
print $fiber->getReturn();
//prints 123456
Fiber::start
(PHP 8 >= 8.1.0)
Fiber::start — Start execution of the fiber
Description
A variadic list of arguments to provide to the callable used when constructing the fiber.
If the fiber has already been started when this method is called, a FiberError will be thrown.
Parameters
-
args -
The arguments to use when invoking the callable given to the fiber constructor.
Return Values
