Firstly, consistency. If I want to include "navigation.php" from
"/index.php", with your system you have to write:
include "includes/navigation.php";
but if you want to include the same navigation menu from
"/birds/parrots.php" then you need to use:
include "../includes/navigation.php";
The path is different, you see. Now, say my site takes on more of a parrot
focus, so I decide to move "parrots.php" out of the "birds" directory and
into my site's root directory, then this breaks the include path, and I
need to change it.
Using include_path makes maintenance a lot easier. I put "navigation.php"
into a directory listed in my include path, then I can use it on
"/index.php" or "/birds/parrots.php" like this:
include "navigation.php";
without having to specify the path to it. I can then move my "parrots.php"
file about as much as I like, and don't need to make any changes to it.
This is much the same way that C programmers work. They specify the file
name of a library they want to include, but not the full or relative path
to it. They rely on the build environment to specify the location of all
the library files.
