![]() That's the next thing I did using mysqli_poll. However, if you were to create a MySQLi connection that contained this code and wrapped API resolvers (or multi-request handlers) each in a Fiber then you could have multiple branches of logic or requests being processed while waiting for the database call to return. log($e) and continue, set to output, or throwīy itself this is pretty basic and involves polluting your code with a lot of Fiber::getCurrent() & Fiber::suspend() calls (just in case you're not in a Fiber you can't just call Fiber::suspend(). A fiber-only "event loop" would look something like this: $fibers = This is actually something I've been working with the last couple of days. Check out for an example of something that is both async/fiber and can sleep for a configurable amount of time. While you can do most things just using Fibers, for something like sleep you'll need to include or build in an Event Loop. The reason your first example isn't async is because sleep is a blocking call and nothing is calling Fiber::suspend to release control of the synchronous thread back to $fiber1->start(). Is there currently a way to run asynchronous tasks using native PHP at the moment?Įquivalent to a Task in C# or Promise in JavaScript. How is this async if ->start() is returning a value to $value? (from ->suspend(.)) How is this different from invoking normal functions?Įcho "Value from fiber suspending: ", $value, PHP_EOL ![]() " nanoseconds.Every time I hear the Fibers topic, there's always a reference to async/await and frameworks that implement async/await.īut I'm not getting how they are related, since I can't get anything async by using Fibers. current ( explode ( " ", microtime ())). You can use either integer or float.Įcho "Process completed at ". ![]() TimeWait ( 5.5 ) //With this call the system will wait 5 seconds and a half. (A little bit better in this situation is to let the 'full seconds' go by a normal sleep command (makes the thread sleep!, and uses minimum cpu)) ![]() You should take into account, if you use the function replacement down here, the CPU will be in use of 99% for the time of execution.
