If you can determine the number of bits on your system, you could use
a different number from 11 on the two systems to get the answer you
want.

if (is_32_bit_machine()){
 $y = $x >> 11;
}
else{
 $y = $x >> 43; //11 + 32 (guess)
}

One hack for detecting 32-bit machine might be this:


Isn't php suppose to handle all this?  This seems odd to me.

I don't see how php can 'handle' people assuming that integers will
always be 32bits - the php code in the encryption algorythm is flawed
because it assumes that all integers are 32bits and doesn't platform
wordsize (terminology?) into account - how can php know that this was
not the intention?
