I'm writing "application" scripts with PHP (such as a FTP server). Usually I run them under Linux.
I tried to run a script on windows, and after some debugging, I found that socket_select() was returning only when the first socket of the read array has data.

Under linux, it works as expected, but under windows, I had to find a way to stop using 100% CPU (usleep not available & socket_select returning instantly if I give all null socket arrays and a non-null timeout).

I'll try with the stream_select() function. It won't change that socket_select() is bogus, that's why I'm posting that.

After some tries, I found that I was using PHP 4.3.1 instead of 4.3.2 (path error for php.exe).

Now the code works well under linux or windows (only the telnet bug : when you use "quit" with telnet the disconnection isn't detected by socket_read() but socket_select() will return immediatly. Seems to be a freature of socket_read : see doc & you'll see that socket_read can return an empty string.).
