Description:
------------
Creating an array with hardcoded number values beginning with a number 0 does not save anything beyond the 0.

This is when done outside of any quotes, single or double.

It works fine when quotes are added to these numbers.

Reproduce code:
---------------
$a=array(
	1980,
	0891
);

print_r($a);

Expected result:
----------------
Array
        (
            [0] => 1980
            [1] => 0891
        )



Actual result:
--------------
Array
        (
            [0] => 1980
            [1] => 0
        )
