my database table structure is like following:

```
wdt        date            teacherid
1       2011-01-11           1001
2       2011-01-11           1002
3       2011-01-12           1001
4       2011-01-12           1002

```

Now what I want to do is select the date field from the table where teacherid="1001" and then return the result as an array like this- array("2011-01-11","2011-01-12")

so that in my view file I can check if a particular data exists in the array result- like following : 

```
 if (in_array("2011-05-18", $date))       // here the $date would be the array result which -
                                        //  I am expecting to get from model via controller
        {
        echo "Found"; 
        } 

```

My controller looks like following:

```
function index(){

    $this->load->model('mod_teacher_workingday');
    $data['date']= $this->mod_teacher_workingday->get();

    $data['main_content']='view_teacher_workingday';
    $this->load->view('includes/template',$data);
  }

```

Would you please kindly show me how my model should look like in order to get the result as an array in my view file and I can check if a particular data exists in that array? Just for your information I am using Codeigniter.

Thanks :)
