New Comment:
Your "expected result" is based on an incorrect assumption.
The lower bound for type "integer" on a 32bit platform is in fact
-2147483648.

Description:
------------
The function var_dump() returns different data type for -2147483647 and
-2147483647-1
--Yipkei Kwok
Reproduce code:
---------------
<?php
$int1 = -2147483648;
$int2 = -2147483647-1;
var_dump($int1);
var_dump($int2);
?>
Expected result:
----------------
float(-2147483648)
float(-2147483648)
The lower bound for data type integer is -2147483647. So, -2147483648
(-2147483647-1) should be regarded as float.
Actual result:
--------------
float(-2147483648)
int(-2147483648)
However, -2147483648 (-2147483647-1) is regarded as int.
