change your fetchData method

public function fetchData()
{
    $sql = " select * from desc_tbl";
    $res = mysql_query($sql);

    $data = array();
    while($row = mysql_fetch_assoc($res)){
        $data[] = $row;
    }

    retrun $data;

}

in your test.php

you can then create a table that will echo out the fetchData()

Also this isn't as much related to your original post but I noticed this or something similar appears in almost all your functions:

$res = mysql_query($sql);
mysql_query($res);

I'm not entirely sure what your logic is here but this is essentially calling mysql_query() once to run an SQL query, and then attempting to call it again but passing a resultset instead of an SQL query, which at best will not do anything. You may need to look up specific examples for how to run a SELECT, INSERT, UPDATE, etc query in PHP. Generally speaking INSERT/UPDATE/DELETE queries you run mysql_query() and then mysql_affected_rows() to check if the change was successful. With SELECT queries you run mysql_query() and then run functions like mysql_num_rows($result) to get the number of rows and mysql_fetch_assoc($result) to fetch a row. Poster above me showed an example of mysql_fetch_assoc() to fetch multiple rows of data.
