Why is there many php.ini files in a system?

How can I make this kind of navigation system on my page?

• I am going to make a webpage, and the problem is with the navigation system. I know programming languages from matlab to c#, but I have some problems with php. I wish to make the navigation system SEO friendly, so my subpages on the site will look like this: site.com/about and NOT this: site.com/index.php?page=about. To do it I have to make a directory system (I guess) where for example in the directory "about" there will be the sub index.php file, which includes the main header from the root directory, then the content of the about page, then the footer.php from the root directory. If I write the code with includes(), the php parser looks for the files in the sub directory which are in the main directory. My question is that how can I set the root dir. in the php to establish a relative navigation point. Also, I guess the parser will look for the stylesheet and the javascript files in the subdir, rather than in the root of the site. Has anyone made such a page? I know it is easy, but I can't make it work,I appreciate every answer and everything that can make this happen. Also I will be glad to receive suggestions on what to look for, take care of when building a site like this. Thank you for every answer in advance. A.

• Answer:

  I am pretty sure it would be easy enough to do, as long as you only have 1 page in each sub-directory with the default page name... like index.php or index.htm. That way anytime you go to the directory it will grab the default page. site.com/about would load site.com/about/index.php site.com/feedback would load site.com/feedback/index.php site.com/contactus would load site.com/contactus/index.php etc.... Not really a good way to setup a site, but it could be done that way. In php you do not need to pass a variable like in your example of site.com/index.php?page=about You can just use any valid filename with a .php extension. Like about.php or contact.php, etc. Your choice. Best wishes and good luck on the site.
