Questions about $_SERVER['DOCUMENT_ROOT']

A couple questions about using $_SERVER['DOCUMENT_ROOT']

I am one level below the config.php file and am in my admin directory. I am having trouble connecting with the database and it is because I think the code cannot see the config.php

I used this to make sure I could find the config.php:

$CONF_PATH = $_SERVER['DOCUMENT_ROOT'];

then

require $CONF_PATH."xxxxx/includes/mysql.php";
require $CONF_PATH."xxxxx/includes/db.php";
require $CONF_PATH."xxxxx/config.php";

I am on a MAC OSX 10.4 Server

The $_SERVER['DOCUMENT_ROOT']; returns

/Library/WebServer/Document/

so it would be logical to concatenate that with "xxxxx/config.php";

Does it matter in what order I place these?

Code:

require $CONF_PATH."xxxxx/includes/mysql.php";
require $CONF_PATH."xxxxx/includes/db.php";
require $CONF_PATH."xxxxx/config.php";

Does your PHP user have permissions to access that file? You can always check using the file_exists function

You should call config.php first as it contains the info to connect to the db.

Thanks.. I changed it and it did the trick.

Just for information Donovan, you must think of includes as a part of the script.

For example,

If I was to write a script like this:
index.php

Code:

<?php
include('info.php');
echo $info;
?>

And I made a script like this:

Code:

<?php
$info='hello';
?>

The output would be as you think, hello.

But in the end, you must think of index.php written like this:

Code:

<?php

$info='hello';
echo $info;
?>

It may not be perfect, but it is how I think of it and I think it's rather easy to remember.
