$values = explode(",",$camp_outlet);

    <?php 
        $theData = explode(",",$camp_outlet);
        if (count($theData) > 0 ){
            echo "<select class=\"form-control\" name=\"outlet\">";
            echo "<option>Select Outlet</option>";

            foreach($theData as $value){ // loop through the data and add the options to the select input
                echo "<option value=\"$value\">$value</option>";
            }

            echo "</select>";
         } else {
             echo "<input type=\"text\" class=\"form-control\" name=\"outlet\">";
         }
     ?>
