Apologies, I didn't mean to sleight the code! I was just reading back from where my error occurred and something that was supposed to be a string was coming through as an array. I believe now that this was in fact just another reflection of my issue. Sorry.

Thanks to your var_dump suggestion I've solved the problem. I could see that there was a redundant level of arrays in the middle. I can see now that I misunderstood this example:

$findstate_sig=array(array($xmlrpcString, $xmlrpcInt));

It's as you suggested on Monday; I was adding an extra array because I thought that was required for multiple signatures. I can see now that there are no extra array levels required, just more elements in the existing array. In other words, even with a single signature an array around it is still required.

Thanks for hanging in there and helping me solve the issue! I would have just moved on to other things without your persistence.

Thanks again,

Sorry, but the spec for system.methodSignature is quite clear on the support for multiple signatures, and the code is also a clear indication of support for multiple signatures:

(assuming lib version 1.2.1)

as far as listing signatures goes:
in function _xmlrpcs_methodSignature(), on line 86 we loop on all the possible signatures of the given method,
and on lines 88-94 we list every single sig

as far as validating sigs goes:
in method xmlrpc_server->verifySignature(), on line 322 we loop over every available sig, on line 326 the number of parameters is checked, and on lines 331-347 the type of the single received param is validated.

To be more clear, here is an example of valid usage:

$sig1 = array ($xmlrpcI4, $xmlrpcString); // return an int, receive a string
$sig2 = array ($xmlrpcI4); // return an int, no input params

$dmap1 = array (
  'method1name' => array (
    'function' => 'foo',
'signature' => array($sig1) // notice that I wrap $sig1 into an array!

$dmap2 = array (
  'method1name' => array (
    'function' => 'foo',
    'signature' => array($sig1, $sig2)

To be sure about what is going on, could you add this as line 86 of xmlrpcs.inc:
and mail back the results?

Thanks. I agree, but $mysig1array and $mysig2array are just regular
arrays. At the moment I use one of them as my (single)
signature, so I
know it works.

 From a quick look at the code it seems that 'system.methodSignature'
doesn't (yet) support multiple signatures. That makes it hard
to debug

(Again, I'm working with 1.2.1 and this may already be fixed in 2.0)

the method sig must be an array of arrays, wheter you have only one
valid sig or more.

If, in your code,

$xrs = new xmlrpc_server(array(
'examples.myFunc' => array(
'function' => 'foo',
'signature' => array($mysig1array, $mysig2array)

mysigarray1 and mysigarray2 are already both an array of
array, I see
how this could generate a warning.

you could try with:
'signature' => array($mysig1array[0], $mysig2array[0])

I see now that such notices are a known issue when running
on PHP 5.
However, it does suggest that multiple signature support is not
perfect! I'll try again when PHPXMLRPC 2.0 is final.

Thanks for your help.

Thanks for the help and sorry to be so long in replying!

I've tried calling 'system.methodSignature' with the
correct (second,
below) form of my method declaration in place, and I get
the following

&lt;br /&gt;
&lt;b&gt;Notice&lt;/b&gt;:  Array to string conversion in
&lt;b&gt;xmlrpc.inc&lt;/b&gt; on line
&lt;br /&gt;
&lt;b&gt;Notice&lt;/b&gt;:  Array to string conversion in
&lt;b&gt;xmlrpc.inc&lt;/b&gt; on line

This of course breaks the response. The same happens if I add my
method using add_to_map().

I appreciate I could suppress the error (via reporting
levels) to make
it work, but I'd rather fix the problem at source. Anyone
seen this
before, please? I don't see that I have any more arrays
than I need!

The first example is wrong, by virtue of php syntax: you are

second declaration wins, and the only valid signature you get is

The second declaration looks ok to me.
Are you sure that you are not mixing up the $mysig1array and
$mysig2array arrays or omitting the return type as first value of
$mysig1array and $mysig2array?

Your best bet is to call a system.listmethods on your
server, and see
what it declares to expose.

If you upgrade to version 2.0 of the lib, you will get for free a
debugger (same interface as you get on
http://gggeek.damacom.it/debugger ) that will do the job
for you, and
show results of the system.listmethods call in a nicely formatted
table - very useful for introspection!



I'm trying to create a method with multiple signatures
and having
problems. I've tried both the following formats (for
illustration, I
actually have four variants):

$xrs = new xmlrpc_server(array(
'examples.myFunc' => array(
'function' => 'foo',
'signature' => $mysig1array,
'signature' => $mysig2array

$xrs = new xmlrpc_server(array(
'examples.myFunc' => array(
'function' => 'foo',
'signature' => array($mysig1array, $mysig2array)

I can confirm the signature arrays themselves are OK by
using them
one at a time. When I combine them in the first form I
get an error
similar to:

Incorrect parameters passed to method: Wanted array, got
string at
param 2

... as it seems to get the various signatures confused.
The second
form yields:

Incorrect parameters passed to method: No method
signature matches
number of parameters

I'm using PHPXMLRPC 1.2.1 with PHP 5.1.1.

Thanks in anticipation of any helpful suggestions.
