The following code segfaults some older (pre 5.1.2) versions of PHP:
$foo = date('c', time());
xmlrpc_set_type($foo, 'datetime');

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
valueValue to set the type
type'base64' or 'datetime'
成功时返回 TRUE， 或者在失败时返回 FALSE。
If successful, value is converted to an object.
Example #1 A xmlrpc_set_type() example
<?php
$params = date("Ymd\TH:i:s", time());
xmlrpc_set_type($params, 'datetime');
echo xmlrpc_encode($params);
?>
以上例程的输出类似于：
<?xml version="1.0" encoding="utf-8"?> <params> <param> <value> <dateTime.iso8601>20090322T23:43:03</dateTime.iso8601> </value> </param> </params>

Once you use the xmlrpc_set_type function, the data is encoded into a PHP object. In your XMLRPC server, in order to access the data you must be able to access the necessary part of the object.
So.. to expend on the example above:
<---------- CLIENT ---------->
$string = "My logging event.";
$date = "20030115T12:22:37"; // Must be this format
$binary = fread($fp, 128);
xmlrpc_set_type(&$date, "datetime");
xmlrpc_set_type(&$binary, "base64");
$xmlrpcReq = xmlrpc_encode_request("log.data", array($string, $date, $binary));
In order to retrieve the binary file data you would need to get the scalar portion of the object:
<---------- SERVER ------------>
$string=$params[0];
$date_obj=$params[1];
$binary_obj=$params[2];
$date=$date_obj->scalar;
$binary_data=$binary_obj->scalar;
// Then you can proceed to write the binary
fwrite($handle,$binary_data);
The problem is that PHP has a string type which is also used to hold binary data and dates. But XML-RPC defines three separate types for strings, binary data, and dates. How do you tell how you want strings encoded? That's where this function comes in.
Suppose the XML-RPC method "log.data" took a string, a date, and a binary object. To tell XML-RPC that the date (which is a PHP string) is a really a date and that the binary data (which is also a PHP string) is really binary data, try:
$string = "My logging event.";
$date = "20030115T12:22:37"; // Must be this format
$binary = fread($fp, 128);
xmlrpc_set_type(&$date, "datetime");
xmlrpc_set_type(&$binary, "base64");
$xmlrpcReq = xmlrpc_encode_request("log.data", array($string, $date, $binary));
Note the reference passing in the calls to xmlrpc_set_type; that enables the function to change the values from strings into what xmlrpc_encode/_request expects (which are objects that include a bonus field that tells the desired XML-RPC type).
