Phil Sturgeon wrote this article on benchmarking.
I am engaged in this technology called ReactPHP.
I have been to their GitHub, but I can’t get around it without an example.
Fortunately, I can use the fil repo.
On line 12, Phil created a loop with ReactPHP.
https://github.com/philsturgeon/nonblockingbro/blob/master/p2-async.php#L12
Then he started using the loop on line 24
https://github.com/philsturgeon/nonblockingbro/blob/master/p2-async.php#L24
My questions:
- What is the purpose of this
$loop? - ReactPHP says it is a simple web server. Does this mean that it replaces nginx or Apache?
- When is the best time to use ReactPHP or any similar technology? When is not the right time to use it?
