跨文件的PHP全局变量 [英] PHP global variables across files

问题描述

好吧，也许我的大脑刚刚关闭，但是我无法使它正常工作.

Ok, maybe my brain is just shut off, but I can't get this to work.

这是完整的代码:

Page1.php:

Page1.php:

<?php
    $something = "hello";
    include "Page2.php";
?>

Page2.php:

Page2.php:

<?php
    echo $something;
?>

所需的输出(导航到Page1.php时):

Desired output (when navigating to Page1.php):

hello

实际输出为空白.我尝试将global关键字放在任何地方，但没有任何反应.我想念什么吗?

The real output is blank. I have tried putting the global keyword everywhere, and nothing happens. Am I missing something?

推荐答案

我无法复制此错误，只能在本地主机上尝试此错误，然后从此处复制并粘贴您的代码.我怀疑您存在某种语法错误.

I cannot replicate this error, just tried this on my localhost and copied and pasted your code from here. I suspect you have some sort of syntax error.

打开错误报告，看看是否有任何错误.

Turn on error reports and see if you get any errors.
