Permanently "global" ?

I have an array/hash that stores path information for my app. As in,
what directory this is in, what directory that's in, what the name of
the site is, what the products are called, etc. It's called $glb.

So, every function so far looks like this:

function something() {
global $glb;
}

over and over and over

How do I make $glb just always be global? I'm assuming there's a way
to do this, otherwise let me know and I'll parachute out of this
language and run back home to perl.

thanks
mrb

That's what a global is supposed to be.


And that's why $GLOBALS is there. When you work with several people,
it prevents from messing with the other people's variables given they
are local unless speficied otherwise. Also when you will re-read your
code in a year, you will know immediatly if your variable is local or
global. Btw, you could also send it as parameter of the function
instead, so that you don't need to change every occurence in all the
functions using it if you change the name of the global variable, plus
it will be easier for re-using the function in other scripts.

Well, the alternative would be having to declare variables as local, like
Javascript. In C/C++ it makes sense, since you need to declare the type
anyway. But for a typeless language, PHP's arrangement is quite reasonable.
It's hilarious sometimes when I see JS code where properties of the window
object are used as looping variables.

Hi and Season's Greetings to all. I have a question regarding the use of a qualifier word "Global". I cannot find any reference to this in Access help, nor in books or on the Internet. "Global" seems to be recognised by Access in at least three cases:- 1) "Global Const". Recently someone in this group helped me resolve a problem, and it involved the use of a Global Const. By Googling "Global Const", I got plenty of hits -- but they...

Anyone here feel that "global variables" is misleading for variables whose scope is file scope? "global" seems to imply global visibility, while this isn't true for variables whose scope is file scope. If you have a variable whose scope is file scope in another translation unit, you have to provide a local declaration to access that variable from the other translation unit. Also, I don't see "global variable" used once in the standard....

I saw in a recent post the :: operator used to reach the global namespace, as in global::MyNamespace I hadn't seen this before, so looked it up in MSDN, which explained it nicely. My question is, do "global" and "::" always go together? Is there any other use for these operators, than as a pair? TIA,

Hello all, I might be missing something here, but am trying to understand the difference between using application-level variables--i.e. Application("MyVar")--and global variables--i.e. public myVar as string, etc. It seems to me that the scope and duration are the same, as they both are there while the application is running, and both go away when it quits. I presume that one difference is that the application state can be "flushed," such...
