It only affects xml-rpc values of string type. It is a separate value from xmlrpc_defencoding, allowing e.g. to send/receive xml messages encoded on-the-wire in US-ASCII and process them as UTF-8. It defaults to the character set used internally by PHP (unless you are running an MBString-enabled installation), so you should change it only in special situations, if e.g. the string values exchanged in the xml-rpc messages are directly inserted into / fetched from a database configured to return UTF8 encoded strings to PHP. Example usage:</p><pre class="programlisting">
|
|
<?php
|
|
|
|
include('xmlrpc.inc');
|
|
$xmlrpc_internalencoding = 'UTF-8'; // this has to be set after the inclusion above
|
|
$v = new xmlrpcval('κόσμε'); // This xmlrpc value will be correctly serialized as the greek word 'kosme'
