[2005-11-29 23:55 UTC] devel at digitalaudiorock dot com

Description:
------------
As of XML_RPC 1.3.3, values received by XML_RPC_Client from a server decoded into the proper data types when using XML_RPC_Decode or the values getval() method. From 1.4.0 forward, these all seem to decode as php strings. Although I logged this for php 5.0.5, it seems true of php 5.0.2 as well as php 4.

Test script:
---------------
<?php

require_once('XML/RPC.php');

$server = 'http://localhost';
$path = '/path/to/server/script';
$method = 'method_that_returns_integer_1';

$t = new XML_RPC_Client($path, $server);
$m = new XML_RPC_Message($method);
$r = $t->send($m);
$v = $r->value();
$dv = XML_RPC_Decode($v);

print "Dump of raw value...\n";
var_dump($v);
print "Dump of decoded value...\n";
var_dump($dv);

?>

Expected result:
----------------
I would expect the dump of the decoded value to be an integer (or whatever type the server returns).

Actual result:
--------------
Dump of raw value...
object(XML_RPC_Value)#3 (2) {
["me"]=>
array(1) {
["int"]=>
string(1) "1"
}
["mytype"]=>
int(1)
}
Dump of decoded value...
string(1) "1"

For testing you can use the following server url:

http://digitalaudiorock.com/users/tdexter/xmlrpctest.php

...and method name:

getint

...or methodname getdouble, which returns a double 1.333. This also gets decoded as a string.

This problem is even worse, since it screws up hash lookups.
Here is a test case:

$xml='<?xml version="1.0" encoding="utf-8"?
><methodResponse><params><param><value><struct><member><name
>123</name><value><string>456</string></value></
member><member><name>hi</name><value><string>there</
string></value></member></struct></value></param></params></
methodResponse>';
$retval = xmlrpc_decode($xml);
print 'var_export whole $retval<br>';
var_export($retval);
while (list($key, $value) = each($retval))
{
print '<br><br>Found key '.$key.'<br>';
$keyExists = array_key_exists($key, $retval);
print 'array_key_exists: ';
var_export($keyExists);
print '<br><br>var_export $retval['.$key.']<br>';
var_export($retval[$key]);
}

In earlier versions the key exists and is retrieved. In
newer versions, it fails.

I'm a little confused by your reply. Jaffes comment refers to xmlrpc_decode. My original comment refers to XML_RPC_decode, which is in fact in the pear XML_RPC code, and in prior versions did return php integers and floats for the corresponding xmlrpc types.
