Odd PHP question

[Kurt Granroth]

Actually, I should have specified that the PHP scripts are all 3rd  
party ones.  If they are scripts that I wrote, then there are always  
ways around it.  But the 3rd party ones invariably do 'dirname' on  
PHP_SELF (or something very similar).  That's why I want to know a  
way around that at a higher-level.  Maybe some php.ini setting or  
somesuch.
