Re: PHP globals aren't really globals

It's somewhat annoying to have to tell the function which variables are global sometimes but overall it makes it easier to avoid stupid mistakes. It is a good push to make me less prone to making things global. Usually I just avoid using globals and then pack what I do use into appropiate arrays and thus save myself most the hassle. In several thousand lines of code I may have one or two global vars called. Boget, Chris wrote:

Yes. But with regards to form variables, all you need to do is make one variable global: $HTTP_POST_VARS it is an associative array that contains all the post variables from the form. Make it global and just loop through it.

exactly, u need to loop to an array to get the globals u want.

No, to the the variables/values that you want.

this is not the idea of global, global is global... if it's set outside of ALL functions it should be available 'with no extra code' to ALL functions, it works that way in all programming language I'm familiar with... why not in PHP? that's what I wanna know, why globals in PHP doesn't really work like globals?

Perhaps I'm missing something. In order to access the value of any variable defined outside the scope of the function, you have to declare it as "global". This is true in every single instance. If you do not, then you cannot access the value of that variable. While it's been a while since I've worked with C, I seem to recall it being the case there as well. And in Pascal. And in VB. Again, it's been a while so I could be wrong (but don't think so). Also, PHP was written in C. Why would they institute a behaviour that was radically different than what is part of the parent language? Chris
