Description:
------------
I have a mysql class. When I create an instance, constructor makes connection to server. Then I can use methods to do something with this connection. If I make 2 instances in the same script and each instance is created to connect to another server, the second connection resource rewrites resource in first class.

Reproduce code:
---------------
PART OF USING:

$this->sql = new c_mySqlEx("first", "frs_svr", "login", "pass");
$this->secondSql = new c_mySqlEx("second", "sec_svr", "login", "pass");

$server_select = $this->sql->dbQuery("db", "query");
$server_record = $this->sql->fetchArray($server_select);

PART OF CLASS:

class c_mySql {
    var $identify;
    var $server;
    var $login;
    var $pass;
    var $connection;
    
    /* cons */
    function c_mySql($conIdentify = "", $conServer = "", $conLogin = "", $conPass = ""){
        $this->identify = $conIdentify;
        $this->server = $conServer;
        $this->login = $conLogin;
        $this->pass = $conPass;
        
        $this->connect();
    }
    
    /* connect */
    function connect(){
        $this->connection = mysql_connect($this->server, $this->login, $this->pass);
        if (!$this->connection){
            echo "error...";
        }
    }

    function dbQuery($db, $query){
        $mysqlDBQuery = MySQL_DB_Query($db, $query);
        if (!$mysqlDBQuery){
            echo "error...";
        }
        else {
            return $mysqlDBQuery;
        }
    }

    function fetchArray($result, $errMode = 1){
        @$mysqlFetchArray = MySQL_Fetch_Array($result);
        if ((!$mysqlFetchArray) && ($errMode == 1)){
            echo "error...";
        }
        else {
            return $mysqlFetchArray;
        }
    }

........

Expected result:
----------------
Each instance can work with mysql on the expected (another) server.

Actual result:
--------------
The second connect resource (in the second resource) rewrites resource in the first instance.
