Hi PHP
when I call socket_create , it blocks and nothing happens.

Here is the code .
I copied it from php.net
I use WebMatrix , IIS Windows. (not Apachy)

error_reporting(E_ALL);
set_time_limit(0);
ob_implicit_flush(); 


$address = '192.168.0.243';         
$port = 1000;
echo "address is : $address --- <br/><br/><br/>" ;

echo "before socket_create ... <br/> " ;
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
echo "after socket_create <br/> " ;
if ($sock == false) {
    echo "socket_create() failed  <br/>" ;
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
    echo "socket_create() failed  <br/>" ;
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}
echo "after socket_create() <br/> " ;

echo "before socket_bind() <br/> " ;
if (socket_bind($sock, $address, $port) === false) {
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}
echo "after socket_bind() <br/> " ;

when I run it , it only displays:
before socket_create ...
and then nothing happens
help!
