Re: [Hessianphp-development] Hessian PHP 1.0.5RC2: Date getting corrupted from Java->PHP?

[Jesse M. <jma...@az...>]

>From looking at Protocol.php:

function readLong(){
  // Thanks Radu-Adrian Popescu
  $data = unpack('N2', $this->read(8));
  $value = $data[1]*256*256*256*256 + $data[2]; // +0.0;
  return $value;
}

This looks a little suspicious:  It's trying to build essentially a double
from 2 signed integers.  It seems extra strange when the long 1174970145000L
comes over the wire as:  $data[1] = 273, $data[2] = -1850894104  .

I wrote some pretty longwinded int to double code by unpacking the bytes:

    function readLong(){
        // Thanks Radu-Adrian Popescu
        $data = unpack('N2', $this->read(8));
        $h = $data[1];
        $l = $data[2];
        $b[] = ($h >> 24) & 0xff;
        $b[] = ($h >> 16) & 0xff;
        $b[] = ($h >> 8) & 0xff;
        $b[] = $h & 0xff;
        $b[] = ($l >> 24) & 0xff;
        $b[] = ($l >> 16) & 0xff;
        $b[] = ($l >> 8) & 0xff;
        $b[] = $l & 0xff;
        $m = 1.0;
        $value = 0.0;
        for ($i = 0 ; $i != 8 ; $i++) {
            $value += $b[7 - $i] * $m;
            $m *= 256.0;
        }
        return $value;
    }

It seems pretty longwinded way of putting together a double, but it does
work (at least for my example -- no big testing done yet).  There's no doubt
a shorter way of manipulating stuff, but it seems tricky since you need to
go from an int to a double.
