IIS vs Apache

First, let me express my apologies for asking so many basic questions; however, PHP is so new to me and I am using a the not so good NT platform (but that is what my clients insists on). As I have stated in other postings, I have PHP 4.0.2 running on Win 2K with IIS 5.0. My database is Interbase 6 and everything runs fine *except* the GET/POST methods do not work. So, I installed Apache and the GET/POST *now work but* Interbase does not run. When I look at the results of phpinfo(), the Extension_Dir is blank under Apache. I only have one php.ini file on my hard drive and it is not changed when I switch between IIS and Apache. Why would the Extension_dir have a value when I run IIS and not have a value when I run Apache? Todd -- Todd Cary Ariste Software todd@aristesoftware.com
