unset $_POST doesn't works

Here is my code http://pastebin.com/DtK8MMtU when user pressing 'Next turn' button, $_POST["turnOver"] is getting set. Then script goes into this section

 if (isset($_POST["turnOver"])) {
                $_SESSION["state"] = 0;
                unset($_SESSION["rolls"] );
                unset($_SESSION["bet"]);
                unset($_SESSION["nextTurn"]);
                $_SESSION["turnNumber"]++;
                unset($_POST["turnOver"]);    
 }

By this row unset($_POST["turnOver"]); i want this block executes only once after user pressed 'Next turn' button, but this executed every time user refreshed page (i saw this by $_SESSION["turnNumber"] value, its increasing all the time i refresh page). Also, here is $_POST var_dump from xdebug:

array (size=1)
  'turnOver' => string ''... (length=9)

It means it is set?

If the user is refreshing the page they will be sending the turnOver POST value each time. Unsetting post will only affect the rest of that page.

Best thing to do is set a session value and set that the first time that turnOver is sent then check against that.

You said

I saw this by $_SESSION["turnNumber"] value, its increasing all the time i refresh page

This is a normal beauvoir since you execute

$_SESSION["turnNumber"]++;

which will keep adding 1 at each refresh. Further more before the line

unset($_POST["turnOver"]);

Your $_POST["turnOver"] is actually set so if you try a var_dump before the unset() command you will see it as set.
