I'M trying to learn PHP but I can't seem to get past the setting up of MySQL and Apache. I am using the book "PHP, MySQL and Apache All in ONE". This is ridicules, once I edited the file httpd.conf in my text editor, the books now tells me to add my PHP directory to my Windows PATH. But it doesn't bother to tell me what that means or how to do that. Keep in mind I am familiar with file paths and directories. Please help someone, anyone.
