NYCPHP Meetup

[William E. Fisher]

Dear Susan, Jose, Joel:

Thank you for your fast and intelligent replies.

Jose, I have been trying to avoid using curl (which I have never used and
don't really understand), but I'll give it a try if it comes to that.

Joel, I'm still working through your links.

I'm unavailable for a few days but I'll respond again on Monday.

(Meanwhile, if anyone has any specific comments about using sockets, I would
still be interested in learning more about what I must have left out of my
code (below).)

Thanks, and cheers,

Bill
