Here's mine. You might have to alter the order of the two 32-bit
components to match your external format. I've used the same names you
might be able to drop it into your tests.

echo "PACKING: ".$i64.PHP_EOL;

$ps = pack('N2', $i64 >> 32, $i64 & 0xffffffff);

list(, $hi, $lo) = unpack('N2', $ps);
$unpack = ($hi << 32) + $lo;

echo "UNPACKED: ".$unpack.PHP_EOL;
