Well, as i remember it right, the possibility exists that the value of
your $phpEx can be manipulated by a _GET or _POST request :
http://www.site.com/script.php?phpEx=some_value
Secondly,the risk exist (especially if your app grows bigger) that you
accidentally use the same variablename...happened to me a few times.
But hey, if you covered all that, then its all a matter of taste i
think.
