Accessing All Global Variables?

Anon

Hi,

Is it possible to gain access to all global variables inside a function as opposed explictly referencing each one?

I know that this is genereally not a good idea, but, I have one function that prints an html form, and another one that process's it. There are a lot of fields, and it's kind of a pain to have to declare each one as global within the function.

thanks,

Brad.

global $GLOBALS;
extract ($GLOBALS);

If you really need to do this you should concider rewriting your code. Functions are best when they only use the variables passed to them.

$GLOBALS is available within functions, it contains every global variable. You can refer to the global variables directly as such :

print $GLOBALS['var'];

A hack to make all globals available is within the function do this : extract($GLOBALS) but that is not at all optimal (read: not a good solution).

I'm aware of this (I have a University Comp Sci degree, trust me, I understand the pitfalls of globals 🙂), but in this case, there its not a risk, and it would overly complicate a simple script to do this.
