versions of PHP. From what I can tell, PHP requires a full path to file_exists() in newer versions, and realpath() will fix it. I noticed that file_exists() doesn't need to have a full path passed to it in older versions, so I just made a fake function, realpath() that will only define itself if realpath() isn't defined. It may or may not work, it seems to work here on PHP 4.2.3, but if it breaks older versions, please *LET ME KNOW* or change it. Because I changed this so quickly, I don't know if everything works exactly. Really, PM or email me if it doesn't. Cross your fingers! :D Thanks! dougk_ff7 dougk_ff7@phpbb.com git-svn-id: file:///svn/phpbb/branches/phpBB-2_0_0@2935 89ea8834-ac86-4346-8a33-228a782c2dd0
