in my current code i use <? include("../_includes/rooturl.php");?> to make links. this way i can change to different servers and just change the rooturl.php file to make all links in my site correct.

there is one problem though, as you see above, the links to the rooturl.php page needs to be relative to where the file is located. this means i can't move files up or down in the folder hierarchy on the site or the links will fail.

is there a way to specify a URL with php and have it as a function that is not relative to a specific place on the server? for example: $rooturl; (<- i made this up, i don't know what the hell i'm doing here so don't take that example literary).


thanks

You could use an absolute path, example:

PHP Code:

<? include("/home/user/www/file.php");?>

This will work anywhere on the server as long as your 'file.php' is in /home/user/www/

This could be the hack for your problem. Its function algorithm uses variable reference method.

PHP Code:

function setRootPath(& $rootPath) {

     if(preg_match("/{$_SERVER['DOCUMENT_ROOT']}/",$_SERVER['SCRIPT_FILENAME'])) {

         //Set root path to document root

         $rootPath = $_SERVER['DOCUMENT_ROOT'];

     }

      if(!preg_match('#/$#',trim($rootPath)) {

         $rootPath = trim($rootPath).'/';

      }

}



//Usage

//Directory tree

//Path: /home/www/

//                        ./_includes/

//                                       ./functions.php

//                        ./_content/

//                                       ./yourscript.php

//                        ./index.php



//yourscript.php

$rootDir = '../'; //always trail with single slash '/'

setRootPath($rootDir);

print $rootDir; //output can be either '../' or '/home/www/'

include $rootDir.'_includes/functions.php'; //include files with path relative to your index.php

i'm guessing /home/user/www/ is the default for any server right? so if my URL is "www.website.com" the above will work? when i login into my server via ftp i'm one directory above the actual url, this folder is just called "/", no /home/user/... am i still on the right track?

the above is not working for me, that's why i'm asking...

include $rootDir.'_includes/functions.php'; //include files with path relative to your index.php 

thanks! would you mind giving a small explanation as to what each command does and how i can use this? how do i format my url etc?

i'm a newb so please be patient

You can do this for the first step:

PHP Code:

print $_SERVER['DOCUMENT_ROOT'];

print '<br />';

print $_SERVER['SCRIPT_FILENAME'];

print '<br />';



//Function declaration

function setRootPath(& $rootPath) { 

     if(preg_match("/{$_SERVER['DOCUMENT_ROOT']}/",$_SERVER['SCRIPT_FILENAME'])) { 

         //Set root path to document root 

         $rootPath = $_SERVER['DOCUMENT_ROOT']; 

     } 

      if(!preg_match('#/$#',trim($rootPath)) { 

         $rootPath = trim($rootPath).'/'; 

      } 

} 

//Preg match is used to compare your current filename with your server default 

//document root. If there is a match, the function will set document root to your 

//server's default.

//The function parameter is passed by reference. It means that it doesn't make a 

//copy of the parameter passed but set an alias for it instead.



//Here

$rootDir = '../'; //always trail with single slash '/' 

setRootPath($rootDir);

//In the function, $rootDir will be bound with $rootPath in the function. when 

//$rootPath changes, $rootDir also changes.



print $rootDir; //output can be either '../' or '/home/www/' 

include $rootDir.'_includes/functions.php'; //include files with path relative to your index

//If your default root path is the same with your server's default, now the 

//string "$rootDir.'_includes/functions.php" should have 

//value "/home/www/_includes/functions.php"

ok.. so what do i do with this file? do include it in my index.php?
i'm sorry but i'm still confused. i'll try to figure it out..

thanks

[nassau]

i found this on php.net:

PHP Code:

<? echo $_SERVER["SERVER_NAME"]; ?>

exactly what i was looking for!

but thanks for all the help! i appreciate it!

Why doesn't anyone just use the default PHP include path? /usr/lib/php.

It's the best way to store your includes without having to worry about what directory level you're one.

in /usr/lib/php i make new folders for each project and include files as so:

<?php include("newproject/file.php"); ?>

Easier than writing code on every page

[nassau]

nekeno, please explain more about that. where is /usr/lib/php? and how does <?php include("newproject/file.php"); ?> know where to find the include? would it not look for a folder, named newproject, within the current folder?
