从另一个文件类函数获取变量[关闭]

Question

I want to get variable from other file's class function.
Something like this :

file lang.php:
<?php
  class lang
  {
    function get()
  {
  $dubs = "dubs";
?>

file print.php:
<?php
  require("lang.php");
  lang::get();
  echo $dubs;
?>

But this returns nothing...

Answer 1

The correct way would be

$lang = new lang();
$dubs = $lang->get();
echo $dbus;
