Why is php bad for websocket server implementation?

Question

PHP

Why is php bad at the moment for implementing a websocket server?
Why does everyone say that it is not worth writing a websocket server on it?

Answer 1

Because PHP is built to die . This is of course an outdated article and there are probably no big problems in PHP 7 anymore, but the same cannot be said about obsolete libraries and frameworks. But if you write in pure PHP, without trying to reuse old, synchronous, single-threaded code, then there should be no problems.

Answer 2

That is nothing, if you follow the memory, then it can work for quite a long time.
