php webservice客户端和服务器端

<?php

$soap=new SoapServer(null,array('uri'=>"http://localhost:7000/serverSoap.php"));
$soap->addFunction('Select');
$soap->addFunction(SOAP_FUNCTION_ALL);
$soap->handle();

function Select()
{
$con=mysql_connect("localhost","root","");
mysql_query("SET CHARACTER SET utf8");
if(!$con)
{
  die('could not connect:'  . mysql_error());
}
mysql_select_db("world",$con);
$result=mysql_query("select * from worldcup where kind=1");
$arr=array();
while($row=mysql_fetch_array($result))
{
   $tmp=array('id'=>$row['_id'],'team1'=>$row['team1'],'team2'=>$row['team2'],'score'=>$row["score"]);
   array_push($arr,$tmp);
}
mysql_close($con);
return json_encode($arr);
}

?>



<?php
mysql_query("SET CHARACTER SET utf8");
$client=new SoapClient(null,array('location'=>"http://localhost:7000/serverSoap.php",'uri'=>"http://localhost:7000/"));
$str= $client->Select();
$str= preg_replace("#\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\1'))", $str);
echo $str;
?>

上面是服务器端，下面是客户端
