Your code works perfectly on my Linux box...
The first time I ran it.
After a 'shutdown' (of your server, not the whole box) though, it bitched
about socket_bind and an already used address...
Sometimes. It seems to be depending on whether I started it with or without
& and then ^C or not, and 'shutdown' seems to only work sometimes...
That doesn't seem right to me... :-)
So maybe you have old processes hanging around, spewing out error messages
to MS-DOS prompts that are long-gone?
Maybe just try a re-boot of the whole box... It is Windows, after all.
Does socket_close() have a return value to indicate success/failure? Don't
end the loop if it didn't really close, I guess.

Like, I think ob_XXXX only affects stuff you echo out to the BROWSER (aka
stdout). I don't think it's gonna do squat for your TCP server...
Won't hurt, though...
Or is this just for that echo line way down below?
I would do:
echo $tcp;
flush();
personally...
But I'm old and don't trust the new functions as much :-)

This ain't right...
No, maybe it is...
You want an assignment there, but you really ought to be doing the trim() on
'quit ' as well, to be nice to bad typists like me :-)
And some parens around the assignment would be nifty.
