Can you explain what situation you're trying to describe? For example, echo
does not write to a socket, so there's more going on than you're telling us.
I know, but I'm not talking about writing to the socket, just echoing to the local Server command line. I would expect the echo'd text to appear in the server terminal window as the script runs--but it only appears when the server terminates. Here's the code:
<?
set_time_limit (0);
$host = "192.168.0.77";
$port = 1234;
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create
socket\n");
$result = socket_bind($socket, $host, $port) or die("Could not bind to
socket\n");
$result = socket_listen($socket, 3) or die("Could not set up socket
listener\n");
echo "Waiting for connections...\n";
$spawn = socket_accept($socket) or die("Could not accept incoming
connection\n");echo "Received connection request\n";
$welcome = "Welcome!\n> ";
socket_write($spawn, $welcome, strlen ($welcome)) or die("Could not send
connect string\n");$input = socket_read($spawn, 1024) or die("Could not read input\n");
socket_write($spawn, strrev($input), strlen ($input)) or die("Could not send\n");
socket_close($spawn);
socket_close($socket); echo "Socket terminated\n";
?>
(Now I start the server:) [Valhalla:~] rene% /usr/local/php/bin/php socket5.php4
(In another terminal window:) [Valhalla:~] rene% telnet 192.168.0.77 1234 Trying 192.168.0.77... Connected to 192.168.0.77. Escape character is '^]'. Welcome! >
(Now, even though the server is running and a socket is connected, the server window does not echo "Waiting for connections...".)
In the client window, I type: > Hello world
dlrow olleHConnection closed by foreign host. [Valhalla:~] rene%
(Now something happens in the server window:) [Valhalla:~] rene% /usr/local/php/bin/php socket5.php4 Waiting for connections... Received connection request Socket terminated [Valhalla:~] rene%
(But when you look at the source code, shouldn't the "Waiting for connections" display as soon as the server is running, or at least when I try to telnet to it? Why would it wait until terminated??)
