Righ!

I have an issue that's been bothering me for some days.

I'm making a smaller class library with a certain hierarchy. These classes lies in separate directories in a dir called, say, MyLib.

/MyLib/rootClass.php

/MyLib/misc/someClass.php

Now. someClass.php requires the rootClass.php which should be done like this:

CODE

require_once('../rootClass.php');


This should work fine. Problem is when I use the 'someClass' from a file in a different directory. Then I can't require the file this way since the current dir is another dir.

Is there a way in PHP to always get the current dir of the file required? So that someClass.php always can reach files in the same dir hierarchy that it lies in itself?

You're looking for the __FILE__ magic constant. That gives the full path to the currently executing file, which can easily give you the directory.

But __FILE__ gives that current dir, is it possible to edit that value to "this dir - 1" so to speak, so if the file lies here:

/root/foo/bar/myFile.php

and I want to reach

/root/foo/otherFile.php

thatn __FILE__ will only give me the /root/foo/bar dir, and I don't want to get that far. Is that possible in any way?

Actually it's __DIR__ I want.

Problem is still here though, check this out

someFile.php
CODE

require_once(__DIR__.'../otherFile.php'); //<--That's sort of what I want to do


someFile is in this dir:
root/foo/bar/someFile.php

and I want to reach this file
root/foo/otherFile.php

can __DIR__ move one step up in the dir hierarcy?

[SOLVED]


require_once(dirname(__FILE__).'/../someFile.php');
