 New Comment:

There is no information about such usage in documentation. (well, maybe that's 
why it does not work)

But if such usage is not documented why syntax:

static $age = 18;

is *valid* outside class?

I agree, this should have same consequences as in C lang.

This feature would also be useful for static (file scope) functions as well.

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
