ciao grazie infinite per avermi risposto , ti voglio fare vedere le due classi magari riusciamo a modificare la classe ... posto la mia ::::
Codice PHP:
class DB{
var $dbcore;
var $host ='localhost';
var $user ='root';
var $pass;
var $name;
    //PHP5 Constructor
    function __construct() {
        global $db_host,$db_user,$db_pass,$db_name;
        $this->host = $db_host;
        $this->user = $db_user;
        $this->pass = $db_pass;
        $this->name = $db_name;
    }
    //PHP4 Constructor
    function database() {
        global $db_host,$db_user,$db_pass,$db_name;
        $this->host = $db_host;
        $this->user = $db_user;
        $this->pass = $db_pass;
        $this->name = $db_name;
    }
 function connect()
 {
  $this->dbcore = @mysql_connect($this->host,$this->user,$this->pass)or die("non riesco a connettermi".mysql_error());
  @mysql_select_db($this->name,$this->dbcore)or die("non riesco selezionare il database");
 }

  function disconnect()
 {
  @mysql_close($this->dbcore);
 }
    function ping() {
        if (!mysql_ping($this->dbcore)) {
            $this->disconnect();
            $this->connect();
        }
    }
    function query($sql) {
        $result = mysql_query($sql,$this->dbcore);

       if( ! $result )
       {
       return false;
       
       }


        return $result;
    }
    function getrow($sql) {
        $result = $this->query($sql);
        $returned = mysql_fetch_assoc($result);
        @mysql_free_result($result);
        return $returned;
    }
    function getlist($sql) {
        $returned = array();
        $result = $this->query($sql);
        while ($row = mysql_fetch_assoc($result)) {
            $returned[] = $row;
        }
        @mysql_free_result($result);
        return $returned;
    }
    function getnumrows($sql) {
        $result = $this->query($sql);
        $num = mysql_num_rows($result);
        @mysql_free_result($result);
        return $num;
    }
} 
questa e la classe originale :
