Bug #21760 was fixed, and it's pretty likely this is the same issue.

Assigning to Wez who might know why streams are borked.

I'm using latest snapshot and I have the same problem. With
PHP_BINARY_READ everything works but with PHP_NORMAL_READ I receive the
following error:

"Warning: socket_read() unable to read from socket [0]: The operation
completed s
uccessfully."

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);
?>

Please provide a complete but short example script that can be used to
reproduce this bug.

It's not the same bugs than http://bugs.php.net/bug.php?id=21760 . Here
it's a Win32 PHP version bug only, since the PHP 4.3.0 version, and
there is always the bug in the last version 4.3.3.

socket_read() always return FALSE, and display this error : "erreur [0]
avec socket_read : OpÚration rÚussie."
(in english it should be "error [0] with socket_read : operation
completed.")

maybe it's because of the socket_select() before the socket_read() ?


PS : it affects all my codes, but only with PHP 4.3.x Win32 version. On
unix or with PHP 4.2.3 all works fine.
