Convert from 64bit number to 32bit number

Question

Trying a lot and just failing..

$x = 76561198005785475;

I want to this number, turn into this:

$y = 45519747;

Answer 1

Try this:

$y = $x & 0xffffffff;

This will truncate your 64-bit value to a 32-bit value, but note that there is absolutely no way to get the 64-bit value back, this is a destructive method.
