This Zend tutorial (http://www.zend.com/zend/tut/tutorial-staub3.php) does explain the concepts pretty well, but I cannot for the life of me get the sample code to run. The user comments noticed a couple typos, and other errors, which I've fixed, but still... no dice. I'm running PHP Version 4.3.4 on Mac OSX 10.2.8. Here's the error message:

Here my code:
------------------
<?
// VARIABLES set_time_limit(0); $server_ip = "192.168.0.200"; $server_port = date("i")."000";
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create
socket\n");
// bind socket to port
$result = socket_bind($socket, $server_ip, $server_port) or die("Could not bind to
socket\n");
// start listening for connections $result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
echo "Waiting for connections...\n";
// accept incoming connections // spawn another socket to handle communication $spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
echo "Received connection request\n";
// write a welcome message to the client $welcome = "Welcome to the Server!\n ".chr(0); socket_write($spawn, $welcome, strlen ($welcome)) or die("Could not send connect string\n");
// keep looping and looking for client input
do
{
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
if (trim($input) != "") { echo "Received input: $input\n"; // if client requests session end if (trim($input) == "END") { // close the child socket // break out of loop socket_close($spawn); break; } // otherwise... else { // reverse client input and send back $output = strtoupper($input); socket_write($spawn, $output) or die("Could not write output\n"); echo "Sent output: " . trim($output) . "\n"; } }
} while (true);
// close primary socket socket_close($socket); echo "Socket terminated\n";
?> -----------------------
Any ideas?
