Access to include($file); in another dir.

Is it possible to have one include directory and access it from sub directories?

I’ll try to explain a little better. If I have the following code:

[code=php]

$file_name = “file_to_access”;
include ($file_name);

[/code]

OK! That’s simple. I know! If I want to access this file but it is in a directory outside of the current one (I need to back out of current, not inside current), what do I write???

I know I will have to change the file name to include said directory but I can’t figure out how to back out of a directory.

In HTML, if you want to back out, you do something like:

[code=html]
“../previous_directory/file_inside.html”
[/code]

By using “../” this backs you out – Can you do this with the PHP function include();?

@CompGeek01Jul 24.2005 — Yup, you sure can.

[code=php]
include("../example/path/tofile.php")

// and

include("../../../example/path/tofile.php");
[/code]

...are all perfectly fine examples of includes. Another option is to use a PHP ini directive setting.

[code=php]
ini_set("include_path","./:../:../../");
include("test.php");
[/code]

...would search the current directory, and the next two up for "test.php" in case you needed to allow flexibility in your file structure.

@bokehJul 25.2005 — if you want to be able to put the script anywhere but not change the path to the include use 'document root'

For example if you templates were in a directory named templates and that directory was on below root (ie non-public) you could access it like this: [code=php]include($_SERVER['DOCUMENT_ROOT'].'/../templates/include.ext');[/code]
If you call your includes like this it doesn't matter what directory or sub directory your script is in.

@rch10007authorJul 25.2005 — Thank you both...

I got both ways you've shown to work.

If I use the $_SERVER option I think I can use it no matter which server I am operating on as long as the directory stays the same...HMMM...I guess that holds true for the other way as well.

My problem was that I didn't include enough "../../" to back out of the directory. I wasn't paying attention to my directory structure. Kick me!

OH!!!!

Is there any advantage to using $_SERVER over "../../"????

@rch10007authorJul 25.2005 — I think I just read the answer to my own question - I get in too big a hurry sometimes, LOL!

(Q) Is there any advantage to using $_SERVER over "../../"????

(A) If you call your includes like this it doesn't matter what directory or sub directory your script is in.

That's a big advantage if your structure gets deep!

Success!
