How does $php_root_path work?

rachelkoh

Hi,

I have 1 big folder (called Research) that has index.php (like a home page) and a few folders (namely install, include, publishers, images, search etc.) in it.

index.php uses functions that are in the files reside in folders include, publishers, images and search. Likewise, functions and files in include, publishers, images and search also use functions and files in those folders.

I seen examples using $php_root_path="." and then global $php_root_path in files in include, publishers etc. I tried and apparently, I messed up the whole thing! ALL THE LINKS (e.g.

<a href=\"$php_root_path/index.php\">
<img src='$php_root_path/images/researchPortalLinkLogo.jpg' 
alt='Homepage' width='820' height='55' border=0></a>

ARE BROKEN! Mainly because I do not understand how $php_root_path="." works.

Can anyone help me please? Thanks!

I dont think php_root_path is a predefined variable.

The examples you saw probably are just using the period in the usual sense, i.e. 1 directory level higher.

yeah,you are right, $php_root_path isn't a predefined variable.
But again, how I make my links and everything work again? (Initially I had files reside in that big folder Research. So whenever I need to include or require any other files, I just go require_once("output_functions.php") .)

P.S. You are really fast in response 🙂 Impressive!

just remove it and try.
might also replace with '..' instead of '.'

basically, if you have a period there, you indicate that that is 1 level higher in the current directory hierarchy.

so, unless /images/researchPortalLinkLogo.jpg lies in the current directory, it wont work.
