My short answer is *don't bother*!
I tried for weeks to get sockets to behave for a similar application
(but for an online flight sim). It seems each incarnation of PHP
screws the sockets code around differently. After a fair while, I
found that some bugs reported in PHP3 are still there.
I also found differences in behaviour between Win32 and Unix/Linux
implementations of sockets. Don't be misled by the online function
references that make it look easy - I found that a fair few of the
routines just did not work consistently.
Also ... check you're getting past your firewall! I used a network
packet sniffer to see traffic actually leaving one machine then seeing
what (if anything) appeared on the other.
