Did you check the apache settings? Looking at the PHP documentation:
http://www.php.net/manual/en/reserved.variables.server.php 'PATH_TRANSLATED'
Filesystem- (not document root-) based path to the current script, after the server has done any virtual-to-real mapping.
Note: As of PHP 4.3.2, PATH_TRANSLATED is no longer set implicitly under the Apache 2 SAPI in contrast to the situation in Apache 1, where it's set to the same value as the SCRIPT_FILENAME server variable when it's not populated by Apache. This change was made to comply with the CGI specification that PATH_TRANSLATED should only exist if PATH_INFO is defined.
Apache 2 users may use AcceptPathInfo = On inside httpd.conf to define PATH_INFO. also this is found for php5:
http://www.php.net/manual/en/migration5.incompatible.phpPATH_TRANSLATED server variable is no longer set implicitly under Apache2 SAPI in contrast to the situation in PHP 4, where it is set to the same value as the SCRIPT_FILENAME server variable when it is not populated by Apache. This change was made to comply with the » CGI specification. Please refer to » bug #23610 for further information, and see also the $_SERVER['PATH_TRANSLATED'] description in the manual. This issue also affects PHP versions >= 4.3.2.
Also a non elegant workaround is:
if (!defined(’MAIN_EXEC_DIR’)) define(’MAIN_EXEC_DIR’, dirname(__FILE__));
Then MAIN_EXEC_DIR would always contain the information you are looking for. Certainly, it’s a pain to have to put this in every file, though.
I think the code that finds out the path should become a little smarter to use different ways to find out what the complete URL is.
