Reproduce code:
---------------
THE SOURCE CODE OF SOAPCLIENT IS THAT: 
<?    
    $client = new  SoapClient  ( "elements.wsdl" , array ( ' encoding ' => ' ISO-8859-1 ' ) ) ; 
        
        try  
              {  
                  $return =   $client ->getElement (Carbono) ;
    echo  " <table border  = 1 >  " ;
    echo "<tr bgcolor = gray  ><td> Column</td>  <td>  content</td></tr> " ;
 echo "<tr><td> Num_Atom  </td>  <td> ' . $return  [ 'num_atom' ]  .  ' </td></tr> " ;
 echo "<tr><td> Nome </td> <td> ' . $return  [ 'nome' ] . '</td></tr>" ;
echo "<tr><td> Simbol </td> <td> ' . $return [ 'simbol' ]  . '  </td></tr> "  ;
echo "<tr><td> Massa_Atom  </td>  <td> ' . $return  [ 'massa_atom' ]  .  ' </td></tr> " ;
echo "<tr><td>  Dens  </td>  <td> ' . $return  [ ' dens ' ]  .  ' </td></tr> " ;
echo "<tr><td> Pto_Fusao  </td>  <td> ' . $return  [ 'pto_fusao ' ]  .  ' </td></tr> " ;
echo "<tr><td> Pto_Ebul  </td>  <td> ' . $return  [ ' pto_ebul ' ]  .  ' </td></tr> " ;
echo "<tr><td> Tipo </td>  <td> ' . $return  [ ' tipo ' ]  .  ' </td></tr> " ;
echo "<tr><td> Orbitais </td>  <td> ' . $return  [ ' orbitais ' ]  .  ' </td></tr> " ;
echo "<tr><td> Estrutura_molecular </td>  <td> ' . $return  [ ' estrutura_molecular ' ] . </td></tr> ";
echo "</table> " ;
}
    catch ( SoapFault  $exception )
                  {  
                      echo   " Error: " ;
                       echo " <b>  {  $exception  ->  faultstring } </b> "; 
        
                   }  
?>

------------------------------------------------------------
THE SOAPSERVER IS THAT:
<?     
    function  getElement  ( $nome)

       {  
           if ( ! $nome)   
             { 
                 throw  new SoapFault (' Client ', ' Param not found');
              }   

        $id =  @mysql_connect ( "www.freesq.org", "alphaX9", "");  
       mysql_select_db ("periodical_table",$id);
   
   if ( ! $id)
   throw new SoapFault  (' Server ' , 'Server not found ');

  $query = " SELECT  * FROM  elements  WHERE name='$name'";
 $result = mysql_query ($id,$query);
 $array=mysql_fetch_array($result);

               if ( $array == null )
                      throw  new SoapFault (' Server ' , 'Client not found ');
               
         return  $array [0];

       }   
     
         $server = new  SoapServer ( "elements.wsdl " , array  (' encoding ' => ' ISO -8859-1 ' ) ) ;  
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA,TRUE);
?>

Actual result:
--------------
SOAPCLIENT Error message: { Object id #2 <fault string> }
