Here's a possible patch, but Wez probably knows better if there's a way
to tell if a windows socket is in blocking mode...

I installed the latest windows build PHP Version 5.1.0RC2-dev and the
socket problem still exists. I get:
Warning: socket_read() [function.socket-read]: unable to read from
socket [0]: The operation completed successfully.
When I put PHP_NORMAL_READ for the read type parameter. Using the
default or PHP_BINARY_READ works just fine for the same line of code.

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.
