Php nusoap not passing content - php

Question

I'm new around this corner as well as programming. I'm trying to create a web service based on nusoap and php so it passes a few values from a mysql database out.
I have looked around many websites (including stack overflow answers) and i found some solutions that i have tried but yet without success. For some reason when i do the client to access the service it always comes empty. After a day looking at this i only see letters now...
If someone could provide a way to a solution i would be much appreciated. Thank you!
Server Side
<?php
include 'nusoap.php';
$server=new nusoap_server();
$server->configureWSDL("demo"."urn:demo");
$server->register(
'gamedata',
array(),
array("estadio"=>'xsd:string',
"nome"=>'xsd:string',
)
);
function gamedata(){
$con=mysql_connect('127.0.0.1:3306', 'root', '') or die ("Erro ao conectar...");
mysql_select_db("testar",$con) or die ("Erro ao seleccionar DB...");
$queryforestadio="SELECT nome,cidade FROM estadio";
//$queryforjogos = "SELECT data, id_selecao1, id_selecao2 FROM jogo";
while($resultestadio = mysql_fetch_array($queryforestadio)){
$estadios[] = array('nome'=>$resultestadio['nome'],
'cidade'=>$resultestadio['cidade'],
);
echo "Message from function: ".$estadios['nome']['cidade'];
}
return $estadios;
}
if ( !isset( $HTTP_RAW_POST_DATA ) ) $HTTP_RAW_POST_DATA =file_get_contents( 'php://input' );
$server->service($HTTP_RAW_POST_DATA);
?>
Client Side
<?php
require('nusoap.php');
$client = new nusoap_client('http://localhost:8048/webservice/index.php');
$response= $client->call('gamedata');
$r = $response;
$count = count($r);
for($i=0; $i<=$count-1;$i++){
echo "This is name: ".$r[$i]['nome'];
echo "This is city: ".$r[$i]['cidade'];
}

Answer 1

This code is pointless/redundant:
$estadios[] = array('nome'=>$resultestadio['nome'],
'cidade'=>$resultestadio['cidade'],
);
You're only fetching the nome and cidade fields in your query, so $resultstadio is already an array of just those two fields and their values.
And then this does NOT match the structure you're building above:
echo "Message from function: ".$estadios['nome']['cidade'];
You probably should have something more like this:
while($resultestadio = mysql_fetch_array($queryforestadio)){
$estadios[] = $resultestadio;
echo "Message from function: ".$resultestadio['nome'] ',' . $resultestadio['cidade'];
