Bug description:Numeric string array key is being implicitly cast to 32bit int
and overflowing
Description:
------------
When trying to use a string array key that contains a number outside of the
32bit integer range, the key is being cast to an integer implicitly by PHP
and is overflowing the 32bit integer limits.
This incorrect casting is present in both 5.3.1 and 5.3.2 (probably 5.3.0),
however 5.1.6 through 5.2.13 do not perform this implicit casting. The
manual indicates that an integer-like key will be cast to an integer,
however that should not be the case when the integer will not losslessly
cast, since that can cause keys to be overwritten.
Test script:
---------------
print_r(array("-2147483649" => TRUE, "-2147483648" => FALSE));
print_r(array("-2147483649" => 1, "-2147483648" => 2, "2147483647" => 3,
"2147483648" => 4));
Expected result:
----------------
Array
(
[-2147483649] => 1
[-2147483648] =>
)
Array
(
[-2147483649] => 1
[-2147483648] => 2
[2147483647] => 3
[2147483648] => 4
)
Actual result:
--------------
Array
(
[2147483647] => 1
[-2147483648] =>
)
Array
(
[2147483647] => 3
[-2147483648] => 4
)
