I'm having some problems referencing a file on my website in a PHP script. Let's say the full path is
www.mydomain.com/img/peggy.jpg
I can't use relative addressing like in
../img/peggy.jpg
because the script is in an include file which is included in several files at different levels.
/img/peggy.jpg
doesn't seem to work either. How do I reference to an absolute path?
TIA

You could define(BASE_PATH, dirname(__FILE__)) in your index.php.
Then use $fileName = BASE_PATH . "/img/peggy.jpg";
You would have to use dirname(__FILE__) . "/img/peggy.jpg".
You can use multiple, as well: dirname(dirname(__FILE__)) ...
http://mydomain.com/img/peggy.jpg, but it doesn't seem to be in the form expected by file_exists; it reports that the file doesn't exist, while it does. Thanks for the reply anyway.
file_exists(dirname(__FILE__) . "/img/peggy.jpg") will return TRUE if the file exists and is not inaccessible.$_SERVER['DOCUMENT_ROOT'] points to the absolute path of the current web root.
sub.mydomain.com. Then I get as full path /home2/mydomain/public_html/sub/img/peggy.jpg. The sub shouldn't be there. Is there a way to get rid of it?Solved by writing the full path explicitly:
/home2/mydomain/public_html/img/peggy.jpg
Note to self: will have to edit this if I ever move to another hosting service. Even my current hosting service (Bluehost) may one day decide to rearrange its file structure.
Other solutions are still welcome!
