Yes. You need to have docblocks in place:
/**
* Echo back a string
*
* @param string $textToEcho
* @return string
*/
function echoTest($textToEcho)
{
return "You said: " . $textToEcho;
}
The docblocks are used to provide type hinting so that the XmlRpc server
knows what variable types are allowed for a given parameter -- this is
both as a security measure as well as to ensure that method signatures
are properly generated.
