Hi Jough,
After getting spooked that you'd managed to find another manifestation
of a bug that I'd thought I'd fixed the other day I was releaved to find
that was not the case - however you have uncovered an interesting
drawback of the PEAR XML RPC lib, in that it doesn't like the use of
"system." at the start of the method name.
I've done some testing and I think I've narrowed it down to that
combination at the start of the methodName. The approx. reason for this
is that the methodName goes through an eval() function which is
confusing PHP when it finds "system." without the quotes.
Hmmmm... XML RPC really needs to have a more flexible and robust way of
specifying which function to call. Using eval() as an integral part of
that only leads to problems in the end. It should not be necessary.
If I had time I'd rewrite that part of the RPC lib. and I may just do
that!
See code following which is essentially yours, play around with
having/not having "system." at the start of the methodName and you'll
see it works without! Perhaps you may find some other combinations which
the lib doesn't like! :-/
===================================================
// SERVER
<?php
require_once 'XML/RPC/Server.php';
function system_load()
{
// stuff...
{
return new XML_RPC_Response(new XML_RPC_Value("return string"));
}
}
$dispatches = array('system.Load' => array('function' =>
'system_load'));
$server = new XML_RPC_Server($dispatches, 1);
?>
// CLIENT
<?php
require_once 'XML/RPC.php';
$client = new XML_RPC_Client('/server_test.php', 'Kali', 80);
$client->setDebug(1); // helps!
$msg = new XML_RPC_Message('system.Load', array(new XML_RPC_Value("test
string")));
$result = $client->send($msg);
if($result->faultCode())
{
// we have an error
echo "Error Code: " . $result->faultCode() . "<BR>";
echo "Error String: " . $result->faultString() . "<BR>";
}
else
{
// no error, you should get some decoded value out
print XML_RPC_decode($result->value());
}
?>
=======================================================
Hope this helps,
Justin

Subject: Re: [PEAR] PHP5 and XML-RPC
Hi There! Thanks for your reply! Sorry it's taken awhile to respond.
Anyhow, I changed my code to the following:
require_once 'XML/RPC.php';
$client = new XML_RPC_Client('/xmlrpc.php', 'localhost');
$msg = new XML_RPC_Message('system.load');
$result = $client->send($msg);
if($result->faultCode())
{
// we have an error
echo "Error Code: " . $result->faultCode() . "<BR>";
echo "Error String: " . $result->faultString() . "<BR>";
}
else
{
// no error, you should get some decoded value out
print XML_RPC_decode($result->value());
}
print XML_RPC_decode($result->value());
And I get the following:
Error Code: 1
Error String: Unknown method
Fatal error: Call to a member function kindOf() on a non-object in
/usr/local/php5/lib/php/XML/RPC.php on line 1083
It seems to say that $client does not have a send method. Surely this
isn't the case?
Thanks! All help is appreciated!! I'll be much quicker to respond
this time!
