var varState            = String(returnObj[varName]["state"]);
var varCity             = String(returnObj[varName]["city"]);

arrDP.push({        //arrDP is array defined
    //Column          Value
    Select          : plid, 
    State           : varState,
    City            : varCity
});

var dp:DataProvider              = new DataProvider(arrDP);
var select:DataGridColumn        = dg.addColumn("Select");
var state :DataGridColumn        = dg.addColumn("State");
var city  :DataGridColumn        = dg.addColumn("City");    
dg.dataProvider                  = dp; //dg IS DATAGRID NAME AND dp IS DATAPROVIDER
}

in short i need some thing like in link below. http://www.iamboredsoiblog.eu/2009/01/10/advanced-paging-and-filtering-in-flex-datagrid/

Have your PHP query with a 'limit [start],[length]' on it. Put buttons on the bottom of your datagrid to requery with the appropriate starting point for the next query.

Also - I've found that trying to read in more than more than a few hundred records really slows down the rendering in my Flex apps. Esp if you are asking for a sort or drawing any sort of custom controls. That's just my $0.10 though. YMMV.
