[PHP] controls "list menu"

[kale]

hy,
I have a list menu:

<select name="select">
    <option value="one">one</option>
    <option value="two">two</option>
    <option value="three">three</option>
  </select>

I want when I select value "two" my page reloads and 
it prints "You selected value TWO". 
How can I do this?

thx 
kale.
