问通过extraParams向存储区传递数组只会给出ExtJS中的最后一个值

EN

for(var i = 0 ; i < store.count() ; i++){
    console.log("id person = " + store.getAt(i).get("ID_PERSON"));
    idArray.push(store.getAt(i).get("ID_PERSON"));
}

console.log("id array = " + idArray);

store = Ext.getStore('borrowerListStore');

store.getProxy().extraParams={
    idArray: idArray
};

store.load({
    callback: function(records, operation, success) {

        var total = operation.request.scope.reader.jsonData['total'];
        var message = operation.request.scope.reader.jsonData['message'];

        console.log("message  = " + message);
    }

});

else if(isset($_GET['idArray'])){

    $idArray = $_GET['idArray'];

    $array = $idArray;

    for($i = 0 ; $i < count($idArray) ; $i++){
        array_push($array, $idArray[$i]);
    }

    $sql = "SELECT * FROM TABLE WHERE ID IN(".implode(',',$array).")";

$result = mysql_query($sql);    

    $res->message .= " Loaded data ";
    $res->message .= " sql = " . $sql;
    $res->message .= " idArray = " . $idArray;
    $res->message .= " array = " . $array;

    $total = mysql_fetch_array($totalquery);
}

message  =  Message start  Loaded data  sql = SELECT * FROM TABLE WHERE ID IN() idArray = 80 array = 80
