stream_set_blocking($SocketFP,1);
- doesn't it open the socket in blocking mode anyway? (not sure how
much sense fflush() would make if it were non-blocking).
I suspect its not relevant, though ISR something about newlines and
flushes on streams - but your script above does have a newline char -
but normally where a line is terminated by a CR and LF, the CR comes
first. This may be a problem - I'd try with a different client but
don't know of a generic tool for Unix domain sockets - nc will work
for a TCP socket though.
I'd also suggest checking the value of $i and what fflush() returned.
