store different post variables in a session array

Question

是否可以将不同的值存储到php中的会话变量中，例如我有一个名为$_POST['sit']的post变量，每次用户提交表单时该变量都使用不同的值，我想存储所有不同的值直到用户停止提交表单后，post变量才会使用，如何将post变量的所有不同值存储到会话变量数组中

You will need to start the session, check for the existence of the post variable, and then push into an array stack within the session. here's psuedo-code:

session_start();
if(isset($_POST['sit'])){
    $_SESSION['sits'][] = $_POST['sit'];
}

Now when you var_dump($_SESSION['sits']) it will hold reference to all of the posted values from $_POST['sit']
