Description:
------------
According to the documentation, socket_read() can return:
1)A string - normal data
2)An empty string "" - the other end closed the connection
3)false - something went wrong.
But it seems to be returning false on connection close.
Reproduce code:
---------------
$buffer=socket_read($socket,2048,PHP_NORMAL_READ);
if ($buffer===false){
echo "Error: socket_read() failed: reason:
".socket_strerror(socket_last_error())." \n";
exit (1);
}elseif ($buffer==''){
echo "Socket $socket returned an empty string. Closing
connection\n";
socket_close($socket);
}else{
echo "Received data".trim($buffer)."\n";
}
Expected result:
----------------
I'm using netcat as a client, and then killing the netcat process with
Ctrl-C to simulate remote host disconnecting.
I expect to see the socket close.
Actual result:
--------------
Actually, the php script exits, because socket_read returns
false instead of "".
This may be a bug in the documentation for socket_read, rather than in
its behaviour.
Thanks for your help - Richard
