Description:
------------
I have tested this on two separate systems running Redhat 8 and redhat 9 respectively.  The Redhat 9 system is running php version 4.3.4 and the redhat 8 is running 4.3.7.

php.ini has not been altered and, in the case of the redhat 8 box (php 4.3.7), it was compiled with the following:
./configure --with-mysql --with-apxs=/www/bin/apxs 

It seems that the bitwise AND operator will not work for values over pow(2,30).  In the case of power 31 it returns a negative value and in the case of power 32 and above it returns 0.

Thank you for your time :)

Reproduce code:
---------------
<?
for($i=28; $i<34; $i++)
{
	$vala = pow(2,$i);
	$valb = pow(2,$i);
	$result = $vala & $valb;
	echo "$i - $vala & $valb = $result<br>";
}

Expected result:
----------------
28 - 268435456 & 268435456 = 268435456
29 - 536870912 & 536870912 = 536870912
30 - 1073741824 & 1073741824 = 1073741824
31 - 2147483648 & 2147483648 = 2147483648
32 - 4294967296 & 4294967296 = 4294967296 
33 - 8589934592 & 8589934592 = 8589934592 


Actual result:
--------------
28 - 268435456 & 268435456 = 268435456
29 - 536870912 & 536870912 = 536870912
30 - 1073741824 & 1073741824 = 1073741824
31 - 2147483648 & 2147483648 = -2147483648
32 - 4294967296 & 4294967296 = 0
33 - 8589934592 & 8589934592 = 0
