想从另一个页面回显一个php变量 [英] Want to echo a php variable from another page

问题描述

我想在页面上回显一个变量，我将其包含在一个不同的页面中。这样可以节省空间并尽可能地将PHP代码与文本数据分开。

I want to echo a variable on a page which I've included form a different page. This to save space and separate php code from text data as much as possible.

在我获取变量的页面中（让我们称之为aa.php）我有：

In the page from where I fetch the variables (let's call it "aa.php") I have:

if ($whatever=="A") echo "somethingA";
if ($whatever=="B") echo "somethingB";
if ($whatever=="C") echo "somethingC";

我将它包含在我希望数据显示的页面上（让我们称之为data.php） ）：

I include it on the page where I want the data to show (let's call it "data.php"):

include 'aa.php';
$whatever = "B";

我想在data.php上显示B，但它不会在页面上回显所有（我猜是因为它实际上是在另一页上？） - 如何在我希望数据显示的页面上回显它，尽可能少的杂乱？

I want "B" to show on data.php, but it isn't echoing on the page at all (I'm guessing because it's actually on the other page?) -- How do I echo it on the page where I want the data to show, with as little clutter as possible?

推荐答案

订单似乎是问题所在：

$whatever = "B";
include 'aa.php';
