New Comment:
First of all, exactly why do you pass data like this between machines?
Secondly: OF course you can't pass huge integers to 32bit system. So
this is expected behaviour. What do you suggest happens in this case?
Try this on 32bit system:
echo (int) 4294967297;

Description:
------------
There is serialized data that made with 64bit integer on 64 bit
system.
On 32bit machine, if unserialize this data, you have result of integer
overflow.
Reproduce code:
---------------
On, 64bit system
echo serialize (4294967296 + 1);
=> result : "i:4294967297;"
On, 32bit system
echo unserilaize ("i:4294967297;");
=> result : 1
Expected result:
----------------
On, 32bit system
echo unserilaize ("i:4294967297;");
=> result : 4294967297
Actual result:
--------------
On, 32bit system
echo unserilaize ("i:4294967297;");
=> result : 1
