Cannot locate file after including it in PHP

So I am trying to include some files in PHP and it's not working.

The file I am writing is in the home directory. There is a subdirectory "D1" in the home directory, and in D1, there is another directory, "D2".

Inside D2 there are a bunch of files. I wrote a class file and stored it in D1. It looks like this:

<?php
include_once('D2/file1.php');
include_once('D2/file2.php');
//ect

class myClass {
   //class stuff
}
?>

So then I write a file inside the home directory like this:

<?php
include_once('D1/myclass.php');
?>

But when I load this file, I get this:

Warning: include_once(file1.php) [function.include-once]: failed to open stream: No such file or directory in /home/D1/D2/file1.php on line 2

"file1.php" is definitely in that directory, so what am I doing wrong?

when including a file, the relative location is relative to the script being called which is the "current working directory". so if script A.php includes ./test/B.php and B.php wanted to include a file under ./test/, it would be relative to A.php. You can create an absolute path using __DIR__ which has the script path and name regardless of where it was included or by using $_SERVER['DOCUMENT_ROOT'] which will point to the document root.

B.php example:

<?php
include(__DIR__.'/C.php');
//will include C.php under the same directory as B.php
?>

the other option is to add D1 to the includes path in php.ini. this tells php to look in that directory for the file when doing an include.

If you are on a linux OS or MAC os you need to be aware of the case for your files, are the D2's capitalized or lower case? etc;

Also I noticed your class myClass { line, does that mean THIS file is being included / used by another file? In which case your relative location of the include file may change.

I'm going to guess you have a permissions problem. Check that the folders/files have the correct permissions to allow access by the web service.
