Yes, it is definitely allowed. The syntactic sugar of using parens
around the include subject is optional, as it is in other parts of php
as well. That said, it's usually better to include the syntactic sugar
so as to make future maintenance concerns easier -- there's less chance
of a future change to introduce an error if it's clear what things are
grouped with what. Much less of a concern in this case, but more of a
concern in, say, compound expressions.
are all equivalent, because php interpolates variable references in
double quoted strings.

Ah, okay, I'm not at all familiar with websockets, so I'm going to have
to step out of this. Good luck with it!
