>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.

I'm having a problem with sending a Date over the wire from Java to
PHP using Hessian 1.0.5RC2. From the java side:
millis: 1174970145000 (Mon Mar 26 21:35:45 PDT 2007)
Is getting turned into a DateTime on the PHP side of:
DateTime Object
(
[day] => 05
[month] => 02
[year] => 2007
[hour] => 03
[minute] => 32
[second] => 57
[_timestamp] => 1170675177.704
[weekDay] => 1
)
Simple test:
public Date testDate() {
Date d = new Date(1174970145000L);
logger.info("Date:" + d);
return d;
}
Output: Date:Mon Mar 26 21:35:45 PDT 2007
$res = $question_proxy->testDate();
pre_print($res);
Output: 2007-02-05 03:32:57

It appears that PHP 5.2.0 defines a DateTime class (for object oriented
playing around with Dates and Times). This causes a fatal redeclared class
error with 1.0.5RC2's "DateTime" class, I suppose.
I worked around by just renaming DateTime to PDateTime ("portable Date
Time?"), and things are back to working.

Hi Jonathan Sorry for the delay, and thanks. Now about your questions: -- Curl: Curl by itself does seem to be faster than using php own socket functions, just because the extra effort of parsing HTTP headers that you *have* to do in raw php, altough the performance gain is almost insignificant. Recently I was performing a few tests over CURL to see if it's possible to use it in the data sending mechanism of HessianPHP. After some time messing with curl_setopt I was able to send binary data to both HessianPHP and Hessian Java, but it has some really ugly caveat. The only way I can make a Hessian service understand binary data coming from PHP is to simulate a file upload(!). Curl will accept a file descriptor (resource) for a file upload, but only it it point to a real file. I tried to simulate it using php streams ( stream_wrapper_register() ), that can act as file descriptors without being a real file, but Curl keeps reject it. So the only way was to save a *real* file with the data payload and then upload it to the remote service (think about tmpfile()). Ugly and slow of course. So I for the time being, I have given up in my efforts to use Curl, it just doesn't behave well, maybe I will try again in a later version of php or someone will give me another hint. -- Zlib compression It's a great idea and there was a discussion in Hessian mail list some time ago about how to incorporate it into the protocol. The C++ version of Hessian, HessianCPP, uses it but it does recognize gzip compressed data by looking a the first 2 or 3 of the data itself, not by a protocol standard. People has proposed several options to incorporate in into the protocol, or keep it simple and use HTTP headers to see if data needs to be decompressed. I am working in the new version of HessianPHP and I am planning to incorporate this feature as soon as possible. Check out Hessian's original mailing list for a deeper discussion: http://www.caucho.com/support/hessian-interest/ |

Manolo, All, Glad to see a binary RPC for PHP - and that you are making efforts in both php4 and 5. I haven't seen any other good binary PHP RPC protocols. I had a couple of questions: - Do you really think using Curl Is faster - or does in just give you finer grained control than having to write all the headers yourself for POST? - What about zlib compression? I guess the problem with zlib compression is that you'd no longer be complying the Hessian protocol? - Jonathan Hendler |

if i want to return this from a hessian php service:
function getAgents()
{
$qr = "SELECT * FROM _agents ORDER BY _order ASC";
$rs = mysql_query($qr);
$agents = array();
$obj->label = "";
$obj->data = "";
$i = 0;
while($el = mysql_fetch_array($rs))
{
$obj->label = $el["label"];
$obj->data = intval($el["data"]);
$agents[$i] = $obj;
$i++;
}
return $agents;
}
How could i convert the result to a c# array ?
Or to what kind of data strcture ?
The same questions, but for java!
c# client : http://www.hessiancsharp.org/
java client : the one from caucho
PLS HELP!!!!
Regards, iongion!
