In PHP, how is variable scope handled in switch statements? For instance, take this hypothetical example: $someVariable = 0; switch($something) { case 1: $someVariable = 1; break; case 2: $someVariable = 2; break; } echo $someVariable; Would this print 0 or 1/2? ...
if(true) { var a:int = 1; } else { var a:int = 2; } In the above actionscript code I get duplicate variable definition error because "a" has been declared twice. But, doesn't "a" exist in two "different" scopes? Is there an elegant way of removing this warning, rather than pulling "a" out of both the scopes and moving it outside...

Hi all, I'm currently developing some things in Python and I have a question about variables scope. This is the code: a = None anything = False if anything: a = 1 else: a = 2 print a # prints 2 If I remove the first line (a = None) the code still works as before. However in this case I'd be declaring the variable inside an "...

Hi, I am trying to optimize my program. I think I understand the basics of closure. I am confused about the scope chain though. I know that in general you want a low scope (to access variables quickly). Say I have the following object: var my_object = (function(){ //private variables var a_private = 0; return{ //...
Hi folks, I'm learning Java, and I know one of the big complaints about newbie programmers is that we make really long and involved methods that should be broken into several. Well here is one I wrote and is a perfect example. :-D. public void buildBall(){ /* sets the x and y value for the center of the canvas */ doubl...

When a drop-down is changed, I check to see if there is data, if there is, I want to clear it out as the drop-down indicates what data to retrie...
I apologize if this is a "duh" question. It seems like the answer should be easily googleable, but I haven't found it yet. I am working on a large Coldfusion application that stores a large amount of session/user data in the Client scope (ie <cfset Client.UserName = "JoshuaC"> ). I did not write this application, and I don't have the lu...
