PHP's include/require

I love this tag... I'm using it the same way most people are using it, for headers & footers...

how do you require something in a folder outside of the one that the script is in? ideally, i'd like a generic tag that will call a certain header in one folder...

i realize its probably not very clear... so here's an example...

lets say i have header.php in the folder /config/ (sub-folder from within the webspace root folder)

i've tried require('/config/header.php'); but that doesn't seem to work... I realize require('config/header.php'); would work for that file in the same directory, but what about files in various directories?

Alternatively, i can't help but notice this part in the error line: (include_path='.;c:\php4\pear')

A supplement question could be, how do i modify the include_path?

i figured it out... =)

include_path was located in php.ini

it was commented out, so i de-commented it... added the path i wanted (the absolute path to the webspace root path)... restarted apache, and it seemed to work...

you could do something like this..

say the root of your webdir is this

/var/wwwdir/html

and you have your config files in /var/wwwdir/config

then you could do this for your include

PHP Code:


		
			
<?

include('../config/config.inc.php');

?>

General purpose way to get root path

I got this code from somewhere else and it works like a charm to get the root path:

PHP Code:


		
			
function path_to_root($path)

   { 

   $pathinfo = pathinfo($path); 

   $deep = substr_count($pathinfo[dirname], "/"); 

   $path_to_root = "./"; 

   for($i = 1; $i <= $deep; $i++) 

      {$path_to_root .= "../";} 

   return $path_to_root; 

} 



// Call it like this when you want to specify a path that starts

// from the root directory:

$path  = path_to_root($REQUEST_URI); 

include($path.'config/config.inc.php');

Doing the trick for me is using the global $_SERVER['DOCUMENT_ROOT'] variable.

Your include would become

PHP Code:


		
			
include( "$_SERVER[DOCUMENT_ROOT]/config/header.php" );

This way you're not depending on the path setting in the php.ini file and is your script or application portable over various web-platforms, as long as they provide this global $_SERVER variable.
