socket_recv help

[vivendi]

Hello, i want to use the socket functions of php but i have a problem with socket_recv().

I have a server running on a computer. This server just waits for a connection.

 

So i created a file, index.php, with code that connects to that server with the socket functions of php.

When the connection is made a immidiatly send a string with the php function socket_send(), the server reacts of this succesfully and immidiatly sends a string back.

 

But this is the part where i have problems, cause php doesn't receive anything at all. Anyone an idea what im doing wrong..??

 

This is my php code so far:

<?php 

$client = array(); 
$client['server'] = "127.0.0.1"; 
$client['poort'] = "7070"; 

if ( !$sock=socket_create ( AF_INET, SOCK_STREAM, SOL_TCP ) ) 
{ 
    die("De socket kon niet worden aangemaakt."); 
} 
if ( !socket_connect( $sock, '127.0.0.1', '7070' ) ) 
{ 
    die("Kon geen verbinding maken met de server: <b>".$client['server']."</b>. Misschien fout?"); 
} 

$buf = "getlist"; 
$recvbuf = ""; 

socket_send ( $sock, $buf, strlen($buf), 0 ); 
socket_recv ( $sock, $recvbuf, strlen($recvbuf), 0 ); 

echo "A: ".$recvbuf; 

?>
