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.

Development environment preparation
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:
c60fee1c85ea21797f3539782d5ebfa1 '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:

9368a5c795691ffefb9892882dae01cd 'Welcome to our recycling website !',

'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.

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

a06c876925a6fc2ce15a0dca29c40cc6connect_error) {

die("数据库连接失败: " . $conn->connect_error);

}

// Query user information

$sql = "SELECT username FROM users WHERE language = '$langCode' ";

$result = $conn->query($sql);

if ($result->num_rows > 0) {

while($row = $result->fetch_assoc()) {
    echo $lang['hello'] . ', ' . $row['username'] . '!';  // 输出问候语
}

}

else {

echo $lang['welcome'];  // 输出欢迎语

}

$conn->close();

?>

The above code will add a drop-down box to the page for switching languages.
Compile and run

Save the above files to the project directory and enter "http://localhost/index.php" in the browser to access the second-hand recycling website.

Conclusion

By using PHP to develop a second-hand recycling website and adding a multi-language switching function, we can provide users with a more friendly and convenient browsing and transaction experience. This feature can help second-hand recycling websites attract more users and expand into a broader market.

The logic in the code examples is for reference only, and developers can adjust and expand it according to actual needs. I hope this article will be helpful to you in developing a second-hand recycling website with multi-language switching capabilities.
