This xmlrpc_encode function doesn't generate the "methodResponse" tag required by some clients.

Using xmlrpc_encode_request seems better:

<?php
$xmlresponse
= xmlrpc_encode_request(NULL, $phpresponse);

xmlrpc_encode(1) generate
<?xml version="1.0" encoding="utf-8"?>
<params>
<param>
<value>
  <int>1</int>
</value>
</param>
</params>

xmlrpc_encode_request(NULL,1) generate
<?xml version="1.0" encoding="iso-8859-1"?>
<methodResponse>
<params>
<param>
  <value>
   <int>1</int>
  </value>
</param>
</params>
</methodResponse>
?>

Another quirk (more of a bug i think) is the automatic encoding of hashes where all keys that begin with a digit between 1 and 9 are lost:
http://bugs.php.net/bug.php?id=37746

Luckily I found a quick workaround. Just append chr(0x00) to your keys and the xmlrpc response will be correct. Maybe this will apply to encoding of hashes for requests too.

Beware this quirk: when you xmlrpc_encode a hash into xmlrpc, numeric keys will not be kept. Even strings containing numbers-only will be lost.

i.e.: xmlrpc_decode(xmlrpc_encode(array('123'=>456)));
returns: array(0=>456);

Apparently this is intentional functionality (see http://bugs.php.net/bug.php?id=21949)

2 workarounds:
1. prepend/append a string (even whitespace) to all keys, and strip them out at the other end. eg array('key_123'=>456);
2. create an array of hashes. array(array('key'=>123,'value'=>456));

I favour the second option because it's more deliberate.

... this also applies to xmlrpc_encode_request()

This function would be used by an XML-RPC server to convert PHP variables into an XML-RPC response.

It would be used within the PHP functions defined using xmlrpc_server_register_method()

Uses PHP variable reflection to assign the correct data types for the XML-RPC response. For example;

<?php
$params
= array ( "one"=>"red","two"=>"blue","three"=>"green" );

$response = xmlrpc_encode ( $params );

echo (
$response );
?>

Produces;

<?xml version='1.0' encoding="utf-8" ?>
<params>
<param>
<value>
  <struct>
   <member>
    <name>one</name>
    <value>
     <string>red</string>
    </value>
   </member>
   <member>
    <name>two</name>
    <value>
     <string>blue</string>
    </value>
   </member>
   <member>
    <name>three</name>
    <value>
     <string>green</string>
    </value>
   </member>
  </struct>
</value>
</param>
</params>

While
<?php
$params
= array ( "red", "blue", "green" );

$response = xmlrpc_encode ( $params );

echo (
$response );
?>

produces;

<?xml version='1.0' encoding="utf-8" ?>
<params>
<param>
<value>
  <array>
   <data>
    <value>
     <string>red</string>
    </value>
    <value>
     <string>blue</string>
    </value>
    <value>
     <string>green</string>
    </value>
   </data>
  </array>
</value>
</param>
</params>

And

<?php
$params
= 1;

$response = xmlrpc_encode ( $params );

echo (
$response );
?>

produces

<?xml version='1.0' encoding="utf-8" ?>
<params>
<param>
<value>
  <int>1</int>
</value>
</param>
</params>

It's useful to be aware of the settype() function (http://www.php.net/settype).

For binary base64 data and XML-RPC iso8601 date times the xmlrpc_set_type() function should be used on a PHP variable before using xmlrpc_encode()

Worth noting, you can use this function to generate fault response xml.

If you pass a pre-determined array into this function, as follows

<?
$myArray = array ("faultCode"=>1,"faultString"=>"Too many params");
$xml = xmlrpc_encode($myArray);
?>

... you will get output much like the following:

<?xml version="1.0" encoding="utf-8"?>
<fault>
<value>
<struct>
  <member>
   <name>faultCode</name>
   <value>
    <int>4</int>
   </value>
  </member>
  <member>
   <name>faultString</name>
   <value>
    <string>Too many params</string>
   </value>
  </member>
</struct>
</value>
</fault>

All that is needed to do here to make it valid XML-RPC is inject some of your own methodResponse tags.
