Ok Man, here is a example of how to use the class
Let says, that you have a table products with this columns: ID, PRODUCT, PRICE
<?php
include("class.DbManager.php");
$db = new DbManager;
$db->setDbParams();

//check if a product already exists
$query = "SELECT id FROM products WHERE product = 'test'";
if($db->checkExists($query))
echo "The product exists";

//insert a new product
$query = "INSERT INTO products(product, price) VALUES('test',10)";
$id = $db->execInsert($query);
if($id!=NULL)
echo "Product Inserted with id $id";

//execute a select
$query = "SELECT * FROM products";
$res = $db->execQuery($query);

//transform the resultset into array
if($res!=NULL)
$res = $db->res2array($res);

//execute delete or update queries
$query = "DELETE FROM products WHERE id = 1";
if($db->execUpdate($query))
echo "Product Deleted Successfully";
?>

ok thanks for explanation but i thought it is something more then that any way thanks

Ok, i made this class to delegate simple db functions to other classes, sorry if it's too simple.
