I need help =( I made a simple TCP/IP server that will talk to someone, but for some reason when typing it will only allow one letter and then stop letting you type. How do I get it so people can type a sentance or more?

Also, it will only allow one person to talk to it. How do I get it to accept lots of connections? (Like up to 10)?

And is there a turorial somewhere on PHP sockets?

Thanks in advance,

Zalbag

Oh and here is the code I am currently using (adapted from the php manual), also if you know of a more efficent way of doing this please tell me

<?php
dl('php_sockets.dll');

/* Allow the script to hang around waiting for connections. */
set_time_limit (0);

$address = 'xxx.xxx.x.xxx';
$port = 10000;

$sock = socket_create(AF_INET, SOCK_STREAM, 0);

socket_bind($sock, $address, $port);

socket_listen($sock, 5);

while (true)
{
    $msgsock = socket_accept($sock);

    $do_again = \"y\";

    while ($do_again == \"y\")
    {
        $talkback = \"\n\rServer: Please input data...\n\r\";
        socket_write($msgsock, $talkback, strlen ($talkback));
    
        $text = socket_read($msgsock, 2);
    
        $talkback = \"\n\rServer: You said '$text'.\n\r\";
        socket_write($msgsock, $talkback, strlen ($talkback));
        echo \"$text\n\";

        $talkback = \"\n\rServer: Would you like to do that again ?\n\r\";
        socket_write($msgsock, $talkback, strlen($talkback));

        $choice = socket_read($msgsock, 1);

        $choice = trim($choice);

        if ($choice == \"n\")
        {
            $talkback = \"\n\rServer: No?...quiting...\n\r\";
            socket_write($msgsock, $talkback, strlen($talkback));
            break;
        }
        elseif ($choice == \"y\")
        {
        }
        else
        {
            $talkback = \"\n\rServer: Invalid answer...quiting...\n\r\";
            socket_write($msgsock, $talkback, strlen($talkback));
            break;
        }
    }

    socket_close ($msgsock);
}
socket_close ($sock);
?>
