Updating php variable [duplicate]

Question

I'm trying to figure out why my PHP var does not update. I tried multiple solutions, not sure if i am doing something wrong, or this does just not work.

Any tips are appreciated.

<form method="post">
  <button type="submit" name="test"> 10  </button>
</form>

<?php
    if(!isset($_SESSION['money']))
    {
       $_SESSION['money'] = 100;
    }

    if(isset($_POST['test']))
    {
        $money = $_SESSION['money'];
        $money++;
        $_SESSION['money']= $money;
        echo $money;
    }
?>

You don't seems to have started the session. Make sure you've put the line session_start(); at the top of your php files

missing session and action

<?php session_start();  ?>
<form method="post" action="">
  <button type="submit" name="test"> 10  </button>
</form>

<?php
    if(!isset($_SESSION['money']))
    {
       $_SESSION['money'] = 100;
    }

    if(isset($_POST['test']))
    {
        $money = $_SESSION['money'];
        $money++;
        $_SESSION['money']= $money;
        echo $money;
    }
?>
