Description:
------------
You cannot store var of type resource or retrieve a var of type resource with shm_put_var or shm_get_var.
It always returns a int(0).

Reproduce code:
---------------
<?php
$SHM_KEY = ftok(__FILE__, chr( 4 ) );
$data =  shm_attach($SHM_KEY, 1024, 0666);

$test1 = array("hello","world","1","2","3");
$test2 = array("hello","world","4","5","6");
$test3 = fopen('t.bla', 'w');

shm_put_var($data, 1, $test1);
shm_put_var($data, 2,$test2);
shm_put_var($data, 3,$test3);

print_r(shm_get_var($data, 1));
print_r(shm_get_var($data, 2));
var_dump(shm_get_var($data, 3));

fclose($test3);
shm_detach($data);
?>

Expected result:
----------------
Array
(
    [0] => hello
    [1] => world
    [2] => 1
    [3] => 2
    [4] => 3
)
Array
(
    [0] => hello
    [1] => world
    [2] => 4
    [3] => 5
    [4] => 6
)

Actual result:
--------------
Array
(
    [0] => hello
    [1] => world
    [2] => 1
    [3] => 2
    [4] => 3
)
Array
