问题描述
限时送ChatGPT账号..我想从其他文件的类函数中获取变量.
像这样:
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;
?>
但这不会返回任何东西...
But this returns nothing...
推荐答案
变量 $dubs 只能在函数 get() 中使用,因为你在那里声明了它.如果你想在外面使用它,有两种选择:或者在函数中返回它的值(在最后添加 return $dubs),然后做一些类似 $a = lang->get(); 的事情,或者让它成为全局的,在类中的任何函数之外声明它.使用哪种方法取决于类和函数的提议;如果要在该类的其他函数中使用该值,请将其设为全局.
The variable $dubs can only be used inside the function get(), because you declared it there. If you want to use it outside, there are two options: or return its value in the function (add return $dubs at the end), and the do something like $a = lang->get();, or make it global, declaring it outside any function in the class. Which method to use depends on the propouse of the class and the function; if you are going to use the value in other functions of this class, then make it global.
