I have a data in my mysql database's table which is Biñan. However, when I try to retrieve it using php, it showed as Bi�an in my dropdown list. 
Here is my sample code:
<?php
   $query = "SELECT * from municipality";
   $res = mysqli_query($conn,$query);
   while($row = mysqli_fetch_assoc($res))
   {
     echo "<option value='".$row['m_id']."'>".$row['m_name']."</option>";
   }
?>
But when I manually echo/insert the character ñ in php/mysql it displayed as is. I have also set the charset to UTF-8.
PROBLEM SOLVED!: I just have to replace the ñ with ñ in my database's table. So it shows ñ in my website.
