These "socket objects" are completely different from fsockopen() "stream 
socket objects", and socket_set_option() doesn't work on those. 
Consequently, you cannot use fgets() and friends to work with sockets 
created with socket_*() and there is apparently no way to wrap sockets 
in streams. It's an already finished application that uses stream-like 
functions (e.g. fgets() and friends) and rewriting it to use raw socket 
recv() and send() would be nasty.
