CGI or Module

[iwaters]

Could someone please explain to me the differnce between the CGI version and the module version. I know the module version is faster etc, but what I want to know is if I have scripts created which work on the module version, how much modifiaction would be needed to move them over to a sever which runs php as CGI.
I need to know becuase I am porting a system from linux, apache and module php to a windows platform which I asume has the cgi version, modules are not possible under windows and IIS or are they?

Many Thanks

From a programming perspective there should be no difference between CGI and a module. One should run faster than the other (CGI will probably always be a bit slower). Module refers to Apache... ISAPI refers to the high-speed version for IIS. So it looks like this:

Platf Slow Fast
IIS CGI Isapi
Apache CGI Module

Platform differences will impact you more than CGI/Module differences. There shouldn't be any of the latter. There will most likely be some of the former. One thing I can think of is authentication/security. It will vary (e.g., $PHP_AUTH_USER works in Apache but not out of the box in IIS). If you're not too worried about security, then differences probably won't be major.
