The second-hand recycling website developed using PHP supports multi-language switching function

With the development of society, the second-hand recycling market is gradually emerging. In order to facilitate users' browsing and transactions, it has become a trend to establish a dedicated second-hand recycling website. In order to meet the language needs of users in different regions, supporting multi-language switching is an essential feature.

This article will introduce how to use PHP to develop a second-hand recycling website and add multi-language switching functionality.

First, we need to prepare a server environment, such as using an integrated development environment such as XAMPP or WAMP. These environments include PHP parsers and MySQL databases.

Create database
Open phpMyAdmin or other MySQL database management tools, create a database and name it "recycle_site".

Create a table named "users" in the database, which will store user information. The table includes at least the following fields: id, username, password, language.

Create a table named "languages" in this database, which will store the supported languages. The table includes at least the following fields: id, code, name.

Insert data
Insert the following data into the "languages" table and "users" table respectively.

languages ​​table:
(1, 'en', 'English')
(2, 'zh', '中文')

users table:
( 1, 'John', 'password123', 'en')
(2, 'Zhang San', 'Password123', 'zh')

Create language file
In the project directory Create a folder named "lang" to store language files.

Create a file named "en.php" in the "lang" folder to store English language text.

Add the following content in the "en.php" file:
$lang = array(
'welcome' => 'Welcome to our recycle website!' ' Logout',
'language' => 'Language',
'hello' => 'Hello',
);
?>

at "lang" Create a file named "zh.php" in the folder to store Chinese language text.

Add the following content in the "zh.php" file:

'username' => 'Username',
'password' => 'Password',
'login' => 'Login',
'logout' = > 'Logout',
'language' => 'Language',
'hello' => 'Hello',
);
?>

Create the index.php file
Create a file named "index.php" in the project directory to display the homepage of the website.

session_start();

//Introduce language files
include 'lang/ ' . $_SESSION['lang'] . '.php';

if(isset($_GET['lang']) && !empty($_GET['lang '])){
