Variable scope issue

trahma

If I have a function call another function, is there a way I can include the variable scope from the parent function in the the called function?

I know $GLOBALS exists for global variables, but what about for variables of a parent function.

For example

$a=1;

function myFunc()
{
$a=2;
myFunc2();
}

function myFunc2()
{
// here is where i need to be able to get
// $a as 2

}

Passing the variable to the function like myFunc2($a) isn't an option for me.

Any ideas? Thanks in advance

If you can't pass the variable then you need to use a global scope variable in both of your functions. But why can't you pass the variable?

I'm developing the template system for a content management script I'm working on. In the template you could do something like {forumPosts} which would call forumPosts() , or {userStats($userid)} which would call userStats($userid). Because the whole system is modular, and other people will be developing modules for the system, I have to do it as dynamic as possible.

From the scope of any given function, you cannot "inherit" the variables from a parent function. They can, however, be passed. (I know you don't want to do this for whatever reason, but...)

See this address
http://www.php.net/manual/en/language.variables.scope.php

where it says:
$LOCALS = get_defined_vars();

Here's how it might work:

function parent (){
$a=5;
$local=get_defnied_vars();
child($local);
}

function child ($inherited) {
echo $inherited[a];
}

parent();

Would display a '5'.

Hope this helps!
