php - Async get request

Question

I'm looking for a way to do asynchronous GET requests in PHP with callbacks, similar to JavaScript's fetch API:

fetch(url).then(Response => Response.text()).then(console.log);

I'm trying to do it like this:

aysnc_gets($urls_array, {echo $result;});

Or I could make a single async request at a time with a simple loop.

I've looked all over and found nothing that works. How would I do this?

I found this website that details curl_multi_* functions, which worked for me.
