Hi PHPers,
I noticed that you have to use keyword "global" in front of globla var.- (one declared
at the top of a script outside any functions ) in order to access it inside a
function. So merely designating a var. global is a little more involved than say Perl
or other languages. You actually have to tell PHP that the function is global.
I see functions , are there subroutine calls. I guess not. A function acts as a
sub when it returns no value . A sub that returns a value is a function.
Thanks
Dexter
