PHP is a programming language widely used in Web development, and in Web development, multi-language and internationalization are very important parts. The latest version of PHP7.0 has many new features to achieve multi-language and internationalization. This article will explore the implementation methods of internationalization support in PHP7.0.
1. Multi-language support
In Web applications, there are users using different languages. In order to allow users to easily access these applications and be able to learn and communicate in their own language, we It is necessary to provide users with an interface in multiple languages. This requires us to support multi-language environments when developing Web applications.
In PHP7.0, there are two main methods of multi-language support: static method and dynamic method.
1. Static method
The static method means that in different language versions of the Web application, the corresponding pages or templates are fixedly stored in different directories. These different directories contain corresponding page or template files in different languages, each file using a language version. When the user selects a new language, the application directly displays the corresponding page in the directory.
In order to achieve static multi-language support, we can define language constants, similar to:
define('LANG', 'en_US');
This code represents the use English is the current language.
Then, use the get_lang_text() function to obtain the corresponding translation text. This function will search for constants in the default language. If the translation corresponding to the constant is found, the corresponding translation text will be returned. Otherwise, the translation text will be returned.
2. Dynamic approach
The dynamic approach means that each request in the web application uses a variable language template. The basic idea of this approach is to check the "accept languages" preference set by the browser for each request and then use this information to decide which language to use.
The implementation method of this method is to store the translated text in the database, and then use PHP to obtain the text stored in the database.
The advantage of using dynamic methods to achieve multi-language support is that users can switch languages in real time and dynamically change the translated text.
2. Internationalization support
Internationalization (Internationalization, referred to as i18n) refers to supporting multiple regions and languages in the application. This means that the application must support multiple user languages and cultures and be accessible through these user languages and cultures and allow users in a specific region to use the application. In PHP7.0, internationalization is supported in the following ways:
- gettext
gettext is a function library that can be used for internationalization in PHP. It provides a standard translation system that extracts text from source files and saves them in translation files. Gettext then translates this text by providing the name and msgid of a translation text field.
- Zend Framework
Zend Framework is a PHP development framework that contains many classes and methods that support internationalization. Zend Framework provides a specialized class - Zend_Translate, which makes it easier for applications to support multiple languages and cultures. Using Zend_Translate, translations of translatable text can be stored in a database and made available in all parts of the application.
- Apertium
Apertium is a free and open source software package for machine translation and language processing. It is a system built in a modular manner and supports translation in multiple languages. Apertium can provide a translation server for PHP developers so that web applications can be accessed through a network connection and obtain translation results.
Conclusion
PHP7.0 supports multi-language and internationalization, allowing developers to more conveniently provide services to global users. In this article, we introduce the main implementation methods of multi-language and internationalization in PHP7.0: static method, dynamic method, gettext, Zend Framework, and Apertium. These methods can make it easier for web applications to support multiple languages and cultures, thereby better serving global users.
