Configuration : PHP 5.1.0b3 (CLI), Win2000 SP4.

I make my first steps in network dev / sockets and I encounter the same
problem.
A simpler complete test case using PHP-CLI instead of the unreadable
sample given sooner.
I want simply connect the client to the "server" and send the msg
"Hello server !" that will be displayed on the server's console...

server.php
=========================================================
<?php
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
    socket_bind($socket, '127.0.0.1', 4567) ;
    socket_listen($socket) ;

    $client = socket_accept($socket) ;
    echo socket_read($client, 256, PHP_NORMAL_READ) ; // Line 7
    socket_close($client) ;

    socket_close($socket) ;
?>
=========================================================

client.php
=========================================================
<?php
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
    socket_connect($socket, '127.0.0.1', 4567) ;

    socket_write($socket, "Hello server !\r\n") ;

    socket_close($socket) ;
?>
=========================================================

So, I launch server.php then client.php, result on server console :

=========================================================
PHP Warning:  socket_read(): unable to read from socket [0]: Opération
réussie.
 in C:\dev\PHP\mines\server.php on line 7

Warning: socket_read(): unable to read from socket [0]: Opération
réussie.
 in C:\dev\PHP\mines\server.php on line 7
=========================================================

Same thing with PHP_BINARY_READ or no 3rd parameter specified :
socket_read( ) returns FALSE and warn us.
No error on client console.

Note that all *seems* OK when I use the following server.php :
=========================================================
<?php
    $socket = stream_socket_server('tcp://127.0.0.1:4567') ;

    $client = stream_socket_accept($socket) ;
    echo fgets($client) ; // Outputs "Hello server !"
    fclose($client) ;

    fclose($socket) ;
?>
=========================================================

So, how should we consider socket extension ? Should we forget it for
stream_*( ) and f*( ) functions ?
Thx :)

I've compilled PHP with cygwin/gcc and no error is produced. However,
the build version from snaps.php.net gives that error.

Ok, this is a short example : (a little echo server)

<?php
error_reporting(E_ALL);

$Port=6669;

if(($Sock=socket_create(AF_INET,SOCK_STREAM,0))<=0) {
        echo 'socket_create() a échoué :
',socket_strerror(socket_last_error($Sock)),"\r\n";
        exit;
        }
if(($Ret=socket_bind($Sock,0,$Port))<=0) {
        echo 'socket_bind() a échoué :
',socket_strerror(socket_last_error($Ret)),"\r\n";
        exit;
        }
if(($Ret=socket_listen($Sock,5))<=0) {
        echo 'socket_listen() a échoué :
',socket_strerror(socket_last_error($Ret)),"\r\n";
        exit;
        }

while(true){
        $MsgSock=socket_accept($Sock);
        if($MsgSock===false) {
        echo 'socket_accept() a échoué :
',socket_strerror(socket_last_error($MsgSock)),"\r\n";
        break;
        }
      else {
            echo '=> Debut de la connexion...',"\r\n";
                $EndTime=time()+15;
                do{
            $buffer=socket_read($MsgSock,1024,PHP_NORMAL_READ);
            if($buffer===false) {
                            echo 'socket_read() a échoué :
',socket_strerror(socket_last_error($MsgSock)),"\r\n";
                                break;
                }
            elseif(!$buffer){
                                continue;
                }
            $buffer=trim($buffer);
                        echo '< ',$buffer,"\r\n";
                        if($buffer=='quit') {
                                break;
                }

            $back='You sent : ['.$buffer.']';

                        echo '> ',$back,"\r\n";
                        socket_write($MsgSock,$back."\r\n");
            } while(time()<$EndTime);

        @socket_close($MsgSock);
        echo '=> End...',"\r\n";
        }
    }
socket_close($Sock);
?>

If you omit the third parameter to socket_read() it seems to work fine.
However, adding PHP_NORMAL_READ causes error as described in the bug
report.

Hello

I have a source which works with PHP 4.1.x to PHP 4.2.x,
it's work perfectly. But with PHP 4.3RC4 (windows version,
client mode) I have this warning :
Warning: socket_read() unable to read from socket [0]: OpÚration
rÚussie. in E:\PHP\KioobFTP\v0.7.1\KioobFTP_SocketMode.php on line 262

Then, the result of the function is FALSE. 
The socket is in blocking mode.
The code is :
$tmp=socket_read($this->stream,4096,PHP_NORMAL_READ);

Do you need others info ?

Thanks.

Bool
