Socket Help

Hi, first post, but I have a socket question.
I have written this PHP script and am executing it through a .bat file.

#!/user/local/bin/php -q
<?php
 set_time_limit(0);
 
 $address = '127.0.0.1';
 $port = 9000;
 
 $sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
 socket_bind($sock, $address, $port) or die('could not bind to address');
 socket_listen($sock, 5);
 
 $client = socket_accept($sock);
 socket_write($client, "Welcome fo-shizzles!
\r");
 
 $input = socket_read($client, 1024, PHP_BINARY_READ);
 
 $output = "Welcome to my PHP socket server. You sent me: $input
\r";
 
 socket_write($client, $output);
 
 socket_close($client);
 socket_close($sock);
?>

When I run & connect, it is fine, yet it returns the answer message & closes the connection when I type the first response character (no matter what it is)

What can I do?
