Re: env vars in included _functions_?

Function do not carry over variables, you would have to tell the function that you wanted to use the variable(s) by using GLOBAL, or you can pass the variable(s) to the function directly. -- phptest2.php <?PHP //phptest2.php function phptest2 () { GLOBAL $PHP_SELF; echo "2: $PHP_SELF<P>\n"; } ?> or -- phptest2.php <?PHP //phptest2.php function phptest2 ($PHP_SELF) { echo "2: $PHP_SELF<P>\n"; } ?> then your call is: phptest2($PHP_SELF); Hope it helps.
