Question

I know this is kind of a hacky thing I’m trying here, but I’m wondering if this is even possible. is there anyway I can access the $x variable in the following code, without passing arguments?

function foo() {
 $x = 1;
 return bar();
}

function bar() {
  //get $x from foo here somehow?
  return $x ? 'stuff' : 'other stuff';
}

I am not sure why, but you can use globals that opens up to a whole thing, but i will show you:

function foo() {
 global $x;
 $x = 1;
 return bar();
}

function bar() {
  global $x;
  //get $x from foo here somehow?
  return $x ? 'stuff' : 'other stuff';
}

Here is the demo: http://codepad.org/fPqUXzyC

It is always better to not use globals and just pass parameters, but if you cannot you could use globals
