Thank you for taking the time to write to us, but this is not

PHP does not support unsigned integers.

Description:
------------
Large integers are being saturated to the maximum signed value
(0x7fffffff) as opposed to being treated as the unsigned values.  

Panic!  I had code that set the high bit in a Permissions variable when
some condition was met.  

After changing PHP versions because of bug 25570, I found user reports
of "Why have I got all these additional permissions?" and "I've now got
Admin rights, OOoooh.  What happens if I run this SQL query in the page
I now have access to?".

Reproduce code:
---------------
define ("BIG_NUM", 0x80000000);
$big_var = 0x80000000;
echo sprintf("%08x, %08x", BIG_NUM, $big_var);


Expected result:
----------------
80000000,80000000

Actual result:
--------------
7fffffff, 7fffffff
