The specified DSN contains an architecture mismatch between the Driver and Application,

Question

Here is the exception that I am getting:

ErrorException in DocketController.php line 65: odbc_connect(): SQL error: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application,

And here is the Docketcontroller.php line number 65:

// Localhost
    $dsn = "test2";
    $conn=odbc_connect($dsn, "QA", "QA");

        if (!$conn) {
            exit("Connection Failed: " . $conn);
            }

    $rs=odbc_exec($conn,$query);
    //odbc_result_all($rs);exit;
    $res=array();
    $fields=array();
    $i=0;
        while($myRow = odbc_fetch_row( $rs ))
        { 
            //echo"<pre>";print_r(odbc_result($rs,1));echo"</pre>";
            $columns= odbc_num_fields ( $rs );
