I want to get the first\_name and the last\_name from a database.  

I select them, but then I'm unable to return both with a space in-between them, and need it to be returned not echoed because I am going to use it as a link for the user profile.

```
function getuser ($id, $field_one, $field_two) {
$query = mysql_query("SELECT $field_one, $field_two FROM users WHERE user_id='$id'");
$run = mysql_fetch_array($query);
return $run[$field_one, $field_two];

}

```

I think the problem is in the last 2 lines

```
$run = mysql_fetch_array($query);
return $run[$field_one];

```
