How to use PHP Developer City to achieve multi-language support function

With the process of globalization, more and more companies have begun to expand their business to the international market. For the e-commerce field, multi-language support is essential. When developing a website, using PHP to implement multi-language support is a common choice. This article will introduce in detail how to use the PHP Developer City to achieve multi-language support.

  1. Prepare multi-language resource files
    First, we need to prepare multi-language resource files. The resource file contains text in different languages, such as Chinese, English, etc. Each language version of the text needs to be represented by a unique identifier. These resource files can be saved in .php or .json format to facilitate subsequent reading and parsing.
  2. Load the corresponding resource file according to the language selected by the user
    On the mall page, we can provide the user with a drop-down menu or button to allow the user to select the language they want to use. When the user selects a language, we need to load the corresponding resource file according to the user's selection.

Loading of resource files can be completed by adding the following code in the PHP code:

  • Get the language selected by the user
    $lang = $_GET['lang '];
  • Load the corresponding resource file according to the language selected by the user
    $res = include("languages/{$lang}.php");
  1. Display text in the corresponding language on the page
    Once we load the resource file for the language version selected by the user, we can display the corresponding text based on the unique identifier. This can be achieved through the following code:

echo $res['welcome_message']; // Display the welcome message

The $res here is an association that contains text in different languages array.

  1. Provide a background management interface to manage multi-language resource files
    In order to facilitate the management of multi-language resource files, we can provide a background management interface. In the background management interface, administrators can add, edit, and delete the contents of multilingual resource files. You can use PHP's file operation functions to complete the addition, deletion, modification, and search operations on resource files.

For example, you can use the following code to add a new language version of the resource file:

  • Get the language version and text information entered by the user
    $lang = $_POST['lang'];
    $text = $_POST['text'];
  • Write the text information entered by the user into the resource file
    $file = fopen("languages/{ $lang}.php", "w");
    fwrite($file, "return [
    ");
    foreach ($text as $key => $ value) {
    fwrite($file, " '{$key}' => '{$value}',
    ");
    }
    fwrite($file, "];" );
    fclose($file);

The above code writes the language version and corresponding text information input by the user into a new PHP file.

  1. Automatic selection based on the user's language preference
    In addition to providing the function of manual language selection, we can also automatically select the appropriate language version based on the user's preference. The user's language preference can be obtained through the following code:

$language = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

According to the user's language preference, You can use PHP's header function to redirect users to the corresponding language version.

Summary:
It is not complicated to use the PHP Developer City to achieve multi-language support. By preparing multilingual resource files, loading the language version selected by the user, displaying text in the corresponding language, and providing a backend management interface to manage multilingual resource files, we can implement a flexible and diverse mall system to meet the language needs of different users. At the same time, automatic selection based on user preferences can also improve user experience. The above is just a simple example, and the specific implementation needs to be appropriately adjusted and expanded according to the specific needs and functions of the mall.
