Bug description:  Static (File Scope) Variables

Description:
------------
Global variables should be able to be declared 'static'.
Static globals, like in C, would only be accessible from the current
file's scope. This would be a good way to protect internal variables used
behind the scenes in a particular file. 

If there is any effective way to protect variables that I overlooked,
outside of PHP classes, let me know. I understand that the possibility of
this depends on how the include/file processing mechanism works.

Reproduce code:
---------------
myvar.inc: 
<?php
static $myvar = 1;
function get_myvar()
{
  global $myvar; // Since its not a true global, this may be different
  return $myvar;
}
function set_myvar($v)
{
  global $myvar;
  $myvar = $v;
}
?> 

test.php: 
<?php
include('myvar.inc');
echo get_myvar().'<br/> ';
set_myvar(0);
$myvar = 10000;
echo get_myvar();
?> 

Expected result:
----------------
1
0

Actual result:
--------------
1
10000
