I tried the server code listed at http://www.php.net/manual/ref.sockets.php.  Everything seems to work except:

a) it spits back extra (whitespace) characters.  For instance, I connect and type "hi".  I get back:
        PHP: You said "hi"
        PHP: You said ""
This always happens, until I get stuck in a loop as above.


b) it spits back part of the code.  For instance, I changed the script to
        $talkback = "PHP: You said '" . urlencode($buf) . "'.\n";
I then get output like:
        PHP: You said 'foo%0D+%28true%29%3B%0A++++close+%28%24msgsock%29%3B%0A%7D+while+%28true%29%3B%0A%0Aclose+%28%24sock%29%3B%0A%3F%3E'.
        PHP: You said ''.
This only happens on the first line of input.   On the server side, I actually get the tail end of the PHP script output.


c) occasionally it gets stuck in a loop.  For instance, I connect and type "foo".  I get back:
        PHP: You said "f"
        PHP: You said "oo"
        PHP: You said "oo"
        PHP: You said "oo"
        ...etc.
This only seems to happen when I do the urlencode() testing above, and not until the 3rd or 4th line of input.


My knowledge is pretty limited, but might this be some kind of buffer overrun?

Should be fixed in CVS (except for "a", which is normal). If
not, please reopen.
