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
