Help needed.
I have 3 domains pointing same directory in my webserver (ISP)
mysite.com
mysite.net
mysite.info

I wanted to use (1) one menu file for all of them, that I load it to the include subfolder.

mywebsite structure

/index.php ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/about.php ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/contactus.php ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/(more files) ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/link/
/link/index.php ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/link/(more php files) ( I use include $_SERVER['DOCUMENT_ROOT']."/include/menu.html"; )
/include
/include/menu.html

Menu File Structure
<li><a href="aboutus.php">ABOUT</a>
<ul><li><a href="aboutus.php">ABOUT US</a></li>
<li><a href="contactus.php">CONTACT US</a></li>
<li><a href="testimonial.html">GUEST BOOK</a></li>

</ul>
</li>

from my php application I use
include $_SERVER['DOCUMENT_ROOT']."/include/menu.html";

Pages on root directory are working well.
/aboutus.php
/contactus.php
/testimonial.html

when I'm on /link directory (subfolder )I got problems
the menu will point to.
/link/aboutus.php
/link/contactus.php
/link/testimonial.html

Getting page no found.

if I'm in a subfolder, how can I do to call the include file, and preserver the root path automatically.

---- let me try to make simpler ----
3 mysites domain
mysite.com mysite.net mysite.info
.com .net .info

/
/index.php
/about.php
/contactus.php
/testimonial.html
/(more files)
/link/
/link/index.php
/link/(more php files)
/include/menu.html

How can I call /include/menu.html from any directory level and maintain same behavior?
------

Thanks!

This is Bad Programming. Look, the whole point of using a computer (outside the world of Micro$heep Push-n-Shove ™) is that your program saves you repetitive tasks. So you write a function

function includemyfile($file)
{ include $_SERVER['DOCUMENT_ROOT'] . '/include/' . $file;
}

Then includemyfile('menu.html'); does all the things above.

But anyway, yes, you have made sure you load a file specified from the server root....



But this is No Good, because it assumes the links are to files in the same directory. Either use links relative to the server root ( href="/aboutus.php" perhaps); or write another function

function linkaddress($filename, $whereweare)
{ ... <work it out yourself> ...
return $address
}

Then you can define a constant in each file WHEREWEARE = '/' or '/links/' or whatever and call

echo linkaddress('aboutus.php', WHEREWEARE);

(for example) to access aboutus.php from whereeverweareatthemoment.

HTH

Done deal.
As you mentioned, I used links relative to the server root ( href="/aboutus.php")

and I avoided to repeat.
$_SERVER['DOCUMENT_ROOT']

Thanks for your suggestions.
