problem with require()

hello, i've this problem with require(). in my script is require "./file"; and php could not find this file. i've found two solutions of thist problem. first is to modify the line in the script to require "file"; and the second is to add a read permission for all directories up to upper directory to the directory with script (ex. dir1/dir2/dir3/myScript.php, so i must set read permission to directory dir1 and dir2) i've this problem in version 4.3.1. in version 4.2.2 worked everything fine. does anybody know another solution of this problem? i don't want to allow the listing in these directories and i am too lazy to modify scripts :-)) (maybe this two hints will help to somebody :-)) Nene
