OK, use this one --> http://uk2.php.net/get/php-5.2.6-win32-installer.msi/from/a/mirror It's the Windows installer
what i am asking is.. we can do a html coding.. then run it in a browser and test it.. how to do that for a php?
HTML is merely rendered in the browser, but PHP needs to be parsed and that's not elegantly done in a Windows desktop environment. I assume this will be run on a hosted web server once it's tested. Do you have access on that server for another domain or subdomain to test it on? That's what I usually do. If I have a site that is live, such as example.com, I'll set up a subdomain, such as 2.example.com, or text.example.com. That way you also know not only that it'll work, but that it'll work in the same environment as the live version.
