much like a Bug !

Slice:

module jf
{
    module nation
    {
        struct UserMessage
        {
            string User;
            string Pwd;
            string Group;
            string Session;
        };

        struct UserConn
        {
            long Id;
        };

        class Ftr
        {
            UserConn Good( int encoding, string usr, string pwd, string grp, string sn );
            UserConn Bad( int encoding, UserMessage user );
        };
    };
};


Server side implement:

    ::jf::nation::UserConn FtrI::Good(
        ::Ice::Int encoding,
        const ::std::string &usr,
        const ::std::string &pwd,
        const ::std::string &grp,
        const ::std::string &sn,
        const ::Ice::Current&)
    {
        ::jf::nation::UserConn cn;
        cn.Id = 0;
        return cn;
    }

    ::jf::nation::UserConn FtrI::Bad(
        ::Ice::Int encoding,
        const ::jf::nation::UserMessage& usr
        const ::Ice::Current&)
    {
        ::jf::nation::UserConn cn;
        cn.Id = 0;
        return cn;
    }

Php test code:

<?php
    Ice_loadProfile();

    try {

        $ftr = $ICE->stringToProxy( "FTR:tcp -p 50000" );
        $ftr = $ftr->ice_checkedCast( "::jf::nation::FTR" );

    } catch( Ice_LocalException $ex ) {
        print_r( $ex );
        return;
    }

    try {

        echo "this test will be passed...<br/>";
        $cn = $ftr->Good( jf_gEncodingPhp, "", "", "", "" );

        echo "this test will be failed...<br/>";
        $um = new jf_nation_UserMessage;
        $cn = $ftr->Bad( jf_gEncodingPhp, $um );

        echo "test ok<br/>";
    } catch( Ice_LocalException $ex ) {
        print_r( $ex );
        return;
    } catch( jf_GenericError $ex ) {
        print_r( $ex->reason );
        return;
    }
?>

run the test, then server side throw a exception:

FTR: warning: dispatch exception: ../../include\Ice/BasicStream.h:112: Ice::Unma
rshalOutOfBoundsException:
protocol error: out of bounds during unmarshaling
identity: FTR
facet:
operation: Bad

and php client side throw a exception:

Ice_UnknownLocalException Object
