I have Apache 2.0.45, ActivePerl, and MySQL installed under Win XP Home. My immediate goal is to learn PHP programming (I have O'Reilly's "Programming PHP"). I plan to use localhost only, there will be no outside connections to my web server, and I am not overly concerned with security. I am a little nervous about installing PHP because I do not understand all the installation issues (e.g, CGI versus ISAPI). I can't afford to get bogged down in these issues, or to botch my install. I could really use a little hand-holding to get me past the install and on to writing PHP. Any help in this regard would be greatly appreciated. I will be forthcoming with any information you might need that I can give. Thanks in advance. Dave Wilson.
