The least integer value (i.e -2147483648 ) is  being treated as float(-2147483648) by the parser. var_dump(-2147483648) returns float(-2147483648).  A integer value should be treated as float, only if the value is beyond the boundary of the integer type. 
The php documentation explains the same here :  &

The Reproduce code confirms that the parser is not handling the Minimum Integer value (i.e, -2147483648) as expected. 

Operating System: RHEL 4
Linux Kernel : Linux 2.6.9
PHP Version: PHP 5.2 (Built on Apr 10, 2007 from
PHP Configure Setup: ./configure

Reproduce code:
$i = -2147483648;

$j = (int)"-2147483648";

Expected result:

String "-2147483648" contains two tokens: "-" and "2147483648".
Since strtol() returns ERANGE when parsing "2147483648", the result number is double.
From what I can see, changing this fact would require major changes to the parser which hopefully nobody is going to do.
Marking as "Won't fix".
