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
