PHP mall development skills: Design multi-language and currency switching functions

In today's era of globalization, more and more mall websites need to support multi-language and currency switching functions to meet the needs of different countries and regions User needs. In PHP mall development, it is very important to design a flexible and efficient multi-language and currency switching function. Here are some practical tips, along with relevant code examples.

1. Design of multi-language switching function

1. Create multi-language files
   First, you need to create a directory to store multi-language files. In this directory, create a file named with a language code, each file corresponding to a different language. For example, en.php represents English and cn.php represents Chinese.

In each multi-language file, define an array to store the corresponding language key-value pairs. For example:

//en.php
$lang = array(
"welcome" => "Welcome",
"hello" => "Hello"
) ;

//cn.php
$lang = array(
"welcome" => "Welcome",
"hello" => "Hello"
) ;

2. Set the default language
   In the website configuration file, you can set the default language. For example, create a config.php file and add the following code:

//config.php
$config = array(
"language" => "en" //Default The language is English
);

Then, in the main file of the mall, introduce the configuration file and load the corresponding multi-language file according to the language settings in the configuration file. For example:

//index.php
include "config.php";
include "languages/".$config['language'].".php";

3. Switch language
   In order to implement the language switching function in the mall website, you can add a drop-down menu for language switching. When the user selects a different language, the page will refresh and load the corresponding multi-language files.

The sample code is as follows:

//index.php
2130f3a5c6c5dbc7bc87b0db26922cef
7026a2fd20aba30987834887c049ee9fEnglish4afa15d3069109ac30911f04c56f3338

//Switch language
function changeLanguage(language) {

  window.location.href = "change_language.php?language=" + language;

}

//change_language.php
8b3a5036aa3432a42e4f09c7f0fcea3e

Through the above code, the user can select different languages, and the page will load the corresponding multi-language files according to the user's selection.

2. Design of currency switching function

1. Create currency file
   Similar to multi-language switching, you first need to create a file to store different currency information. In this directory, create a file named after the currency code, each file corresponding to a different currency. For example, usd.php represents the U.S. dollar, and cny.php represents the Chinese yuan.

In each currency file, define an array to store the corresponding currency and exchange rate information. For example:

//usd.php
$currency = array(
"symbol" => "$",
"rate" => 1 //The US dollar exchange rate is 1
);

//cny.php
$currency = array(
"symbol" => "¥",
"rate" => 6.5 //RMB The exchange rate is 6.5
);

2. Set the default currency
   In the website configuration file, you can set the default currency. For example, add the following code to the config.php file:

//config.php
$config = array(
"currency" => "usd" //Default currency For USD
);

Then, in the main file of the mall, introduce the configuration file and load the corresponding currency file according to the currency settings in the configuration file. For example:

//index.php
include "config.php";
include "currencies/".$config['currency'].".php";

3. Switch Currency
   In order to implement the currency switching function, you can add a drop-down menu for currency switching. The user selects a different currency and the page refreshes and loads the corresponding currency file.

The sample code is as follows:

//index.php
c8eb887d0e3333b60ecbff9b7ee00795
84e0f2403ee3bf092509644ef59c513cUSD4afa15d3069109ac30911f04c56f3338
c234cbe12f8edf48208db6c030d3271fCNY4afa15d3069109ac30911f04c56f3338
18bb6ffaf0152bbe49cd8a3620346341

3f1c4e4b6b16bbbd69b2ee476dc4f83a
/ /Switch currency
function changeCurrency(currency) {

  window.location.href = "change_currency.php?currency=" + currency;

}
2cacc6d41bbb37262a98f745aa00fbf0

//change_currency.php
4dbdbcc708067f8675e3ad5451b8953c

Through the above code, the user can select different currencies, and the page will load the corresponding currency file according to the user's selection.

Summary
Through the above techniques, we can easily implement the multi-language and currency switching function of the PHP mall. Set up multi-language and currency files, and combine them with configuration files to dynamically load corresponding files according to the language and currency selected by the user to provide users with a better shopping experience.

Of course, the specific implementation method can be adjusted according to project needs. The above is just a simple example, I hope it will be helpful to the multi-language and currency switching function in PHP mall development.
