从文件内容中获取变量

Question

I have php language files and i'm including to my project.

For example: content of en.php

<?php
$lng["home"]="Home Page";
$lng["my_account"]="My Account";
$lng["administrator"]="Administrator";
$lng["logout"]="Logout";

I want to change the file content in administration page.

Since the file is included, $lng variable already defined. So when I include the file again it overwrites the existing $lng variable.

I did this by changing the key of the old variable. Like this:

$old_lng = $lng; 
include ("file"); 
$last_included_lng = $lng; 
$lng = $last_included_lng;

is that best way?

Answer 1

Include the file.

include 'en.php';

Then all of your $lng items will be overwritten, it essentially runs the content of en.php as if it were written in the same file.

Answer 2

A way to be independent from the variable name is to return the array directly.

That will look like:

<?php
return [
    'home'       => 'Home Page',
    'my_account' => 'My Account',
    // and so on
];

You can assogn this by using $foo = include('en.php'); .
