在php文件中调用函数并传递JavaScript变量

Question

I have a file.php and inside a function. Javascript Side, I use Ajax.

$.ajax({
  type: "POST",
  url: "file.php",
  data: {param1: params1, param2: params2...},
  complete: function(data){
   /* code */
  }
});

Now in the file file.php, a function login exists. My question how can I call the function login ? Thanks.

function ft_login($login, $password) {
    $u = new KVObject();
    $u->collection = "users";
    $u->loadFormArray(["login" => $login, "password" => $password]);
    if ($u->obj_id == null)
        return ["ERROR" => "Bad creditial"];
    if ($u->status == "blocked")
        return ["ERROR" => "Account need to be activated"];

    $token = md5(time());
    $_SESSION[$token] = $u->dataObject;
    return ["token" => $token, "user" => $u->dataObject];
}

The whole php file is executed. So if you call ft_login inside file.php it gets executed. You can pass your parameters to that function.

Dont forget to json_decode your parameters.
