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).
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 following code segfaults some older (pre 5.1.2) versions of PHP:
$foo = date('c', time());
xmlrpc_set_type($foo, 'datetime');
Please upgrade before reporting as a bug.
