No, the problem is as follows. I want to get all my available

the script will hang here because there will be no reply from

few words I send a presence stanza and waiting for a reply which
will never arrive because there are no contacts. As far as I
understand PHP doesn't not support non-blocking SSL streams.
Is there a way that my presence will always return something or do
I have to write everything in events and there is no other way?
There's no other sane and sensible way... But...
If, for some reason, you're unable to use non-blocking sockets, the
solution is to ensure that data will be present within a short time
period after you start to poll.
The simplest method for that would be to send an <iq/> before you
poll. You want to send it somewhere that you can reasonably trust to
respond, and you don't want it to harm anything, so I'd opt for a
XEP-0199 to the server.
This is, of course, a major hack, and I'd much recommend avoiding it
if at all possible.
