PHP如何在配置文件中处理不同的语言？

Question

I am working on a project and there are going to be 3 different languages: English, French and Spanish. This will be defined when the user signs up.

Now in my config file I have the following:

define("DEFAULT_SLOGAN", "The default slogan will go here.");

Until I started realizing that I needed to accept different languages.

The user has an assigned language code (EN, FR, SP). How would I go about having different language strings for each page? Would I need to have something like this:

define("DEFAULT_SLOGAN_EN", "Slogan in english");
define("DEFAULT_SLOGAN_FR", "Slogan in french");
define("DEFAULT_SLOGAN_SP", "Slogan in spanish");

And for each string just have 3 different versions of it? Not too sure the best way to approach this.

Thanks!

Answer 1

A simple strategy that is often used are arrays:

$lang['en'] = array(
    'DEFAULT_SLOGAN' => 'The default slogan will go here.',
);
// Same for other languages

Then, in your actual code, make sure that $lang is available (you can use the global keyword for this) and use these arrays.

Answer 2

A better approach would be to create

• locale_definitions_EN.php containing

  define("DEFAULT_SLOGAN", "The english default slogan will go here.");

• local_definitions_FR.php containing

  define("DEFAULT_SLOGAN", "The french default slogan will go here.");

etc. and then do something like

include "locale_definitions_$userLocale.php";

This has the advantage, that you don't need the memory to hold the unused other language constants.
