require_once()

[PHPdev]

Can someone please help me understand why this works?

I have 3 files settings.php, inc.php, and index.php

The inc.php is in a directory under the root of the site called inc
Settings.php and index.php are both in the root of the site

settings.php

$_PATH = "/home/site/";

inc.php

require_once("settings.php);
function getdata()
{

}

index.php

require_once($_PATH."/inc/inc.php");

Now if index.php requires $PATH to get to the inc.php, and $PATH is not set until settings.php... How can it ever find the inc.php?

I know this is kind of confusing but I'm confused...

Thanks

Check your php.ini file. There is a setting for the 'include' directory.

So, because you can include the first file, it is in your 'include' directory according to your php.ini file.

If you root www directory is called "www" and you have an include directory called "include", AND your php.ini file has "www" set as your include directory, you can do this:

include("file.inc");
/ means include www/file.inc /

if you did:
include("path/to/file/file.inc");
/ means include www/path/to/file/file.inc /

Does this help you any?

The php.ini file appers to be using the UNIX: pats, which my www directory is not in.

But what I think is happening is that the $_PATH is not set to anything thus it just uses the relative path to the www directory. I made a mistake in my previous message the require_once() should read

require_once($_PATH."inc/inc.php");

I think not haveing the leading / following the first " allows it to use the relaive path...
