mysql_select_db("portal", $con);

$query = "SELECT tag_name FROM tags";
$result = mysql_query($query);

<select name="tag_name" id="abc">
<option size=30 selected>Select</option>
<?php
while($array = mysql_fetch_assoc($result)){
?>
<option value ="<?php echo $array['tag_name'];?>"><?php echo $array['tag_name'];?>
