使用PHP标头重定向到同一页面不会从URL中删除GET请求

Question

I have a hangman game. My problem is that when they get to the win screen, they can refresh it infinitely and each refresh will increment their amount of wins (or losses if they lost), as it checks if the word is complete, it is, and ups their points.

I now made a SESSION variable to tell whether or not they have won. If they have, it resets the game.

My problem is that when they refresh with the GET request in the URL (how do I guesses) such as ...index.php?guess=G the game will refresh with G being guessed. I thought a header with Location set to index.php would get rid of the GET request.

Here's my detecting code:

    if (isset($_SESSION["won"]) && $_SESSION["won"]) {
        reset_game();
    }
    else if (isset($_SESSION["lost"]) && $_SESSION["lost"]) {
        reset_game();
    }

And the reset_game() function:

    function reset_game() {
        $_SESSION["word"] = generate_word("dictionary.txt");
        $_SESSION["word-progress"] = turn_to_underscores($_SESSION["word"]);
        $_SESSION["chances-left"] = 9;
        $_SESSION["guesses"] = array();
        $_SESSION["incorrect-guesses"] = array();

        header('Location: index.php');
    }

Why isn't this working?

Answer 1

I believe header("Location: index.php"); will remove all the get parameters from the URL.

I think you need to check whether your application did call the function
