How Are You Accomplishing Your i18n? 117

Posted by Cliff from the eighteen-letters-between-the-i-and-the-n dept.
cobrabyte asks: "My team has recently been given the task of implementing internationalization (i18n) in our MySQL databases (PHP-interfaced). Essentially, for every article X, we need it presented in any number of languages (once translated). As we were working on gathering the necessary procedures, we were very surprised to find that there's not much organized information regarding i18n using MySQL and PHP.

            Ask any government that supports multiple official languages (Canada, Switzerland, ...). You translate into the other language(s) using professional translators. Period. You can give them the most powerful automatic translation tools available, and multiple language dictionarys (e.g. English-French) but in the end you need a human professional translator to make translations worth reading.

            -without having to write a complete localized version for each language.

            You need to make the content management system (CMS) language aware, and you need to localize all your templates. Then you need to add a key to your article database for language, so the user can retrieve article 101 in either english or french.

      I18n/localization is one of those tasks that has *lots* of questions that will need to be resolved... often you won't even know about all of the issues to resolve until you start digging into it.

      I sorted out the i18n design for a project recently, so I can share some insights on the process. My project used Java/JSP, but the problems are mostly the same. One of the most important points to be made is that you *need* to sit down and design it all the way through -- this is not a "feature" that can be easily added in when you need it later (and extreme programming teams can get hosed on this one pretty easily).

      Things to consider (in the sequence of a request for simplicity's sake):
      1) How will you know what language a user wants (first time, and on subsequent pages)? The user should be able to select/change their preference (though you could use their browser-reported locale as a guess), and they should be able to *bookmark* the homepage in their language. You could use a cookie, and redirect from the basic homepage based on that. Personally I avoid depending on cookies where possible, I didn't want to have duplicated directory structures, and I didn't want an added param on every request, so I used multiple *subdomains*, one per supported locale. They all mapped to the same IP, same application -- but in the web application I could check the requested URL and set the locale (and build the page) correctly using that. There were links on the top of the homepage to switch languages -- which would just flip to the proper subdomain. (Important note -- this complicates getting a cert for SSL, since that's tied to the domain... keep that in mind).

      Once you know what language you're using, build the page... this will probably involve getting data out of the database and displaying some of it.

      First, make sure your tables support whatever character set the languages will need. Then make your data design carefully. You need to make sure that any data in the database that will show up onscreen: product descriptions, category names, and ALSO prices (you probably have to give prices in various currencies, right?).

      Building the page -- you'll need more PHP-specific advice here, but the idea is that you need to get text and possibly images that are language-specific for each page. The general choices are:
      * Use a single PHP file for the content (e.g., a form for registration info), and get the text displayed from locale-specific files (so for the "name" label over that field, you'd grab the proper translation).
      * Maintain a separate PHP file for the content in each language, plug the proper one into the template.

      The first option is better if your content is mostly short bits of text -- but if there are larger chunks of text it gets hard to read (and if the whole page is text -- like a privacy policy page, etc. -- the second option may make more sense). Personally, I supported both options.

      What else? Don't forget that formatting of currency, numbers, dates, and times will vary by locale. Don't forget to review any Flash animations, dropdown menus, popup calendars, etc.. these will need to support changes based on locale. Organize your resources carefully, so that a simple substitution in the path will get you the right image, content file, etc. (e.g., images/fr_CA/whatever.gif).

      The problem is you speak English. There is a good chance that you speak no other language. Since nearly everything is written in English first these days, you don't care about these issues.

      Many of those who care about i18n do not speak English at all! To these people even spelling the word out gives no help. In fact it is less helpful because they have to learn this large symbol. (There is no reason to assume they even know the Latin alphabit, so they will not think to learn each letter separately)

      Of those who speak English, many do not speak it fluently. Often they speak English as a first year student ("hello, my name is"), and they know how to look words up in their English-whatever dictionary.

      Of course English is the dominate second language in the world. There are plenty of people who speak English fluently as a second language. They often have trouble with the creative spelling English came up with. Words with 20 letters are hard for anyone to spell, so it would be no surprise if they have trouble spelling it.

      The goal is one symbol that is easy for everyone to recognize. No matter what language the page is written in, if you see "i18n", you know you are in a location where people are interested in translation. This is often enough for some educated clicking to find the same information in your language.

      i18n may not be a good abbreviation. However can you come up with a way to represent the concept to all 6+billion people on earth?

        Of course English is the dominate second language in the world.

        In IT, English holds the majority by far. And Spanish doesn't even come in second - You have Japanese and German as distant seconds, with Hebrew and French as dark-horse thirds.

        Attempts at internationalization simply hinder the adoption of English as the next ubiquitous academic language. Much like Greek and Latin during the Roman empire - The rabble may all speak Spanish, but those who want to appear educated speak English. Of course, Latin later went on to hold the same place, so perhaps some day Spanish will function as the language of the academic elite.

        Many of those who care about i18n do not speak English at all!

        I don't think that needs an exclamation mark - It doesn't come as a particular surprise to anyone. If you speak English, you don't have the least interest in "internationalization", which basically means "Make it accessible to people who don't speak English".


        And I don't write this as a xenophobic rant... I regularly use programs written by Japanese coders, and a few in German. And do I sit around complaining about how those coders, who already have given me something I find useful, should do extra work unrelated to the purpose of the program to make those programs more friendly to me? No. I recognized my inability to read the menus and such as a shortcoming in myself, and made the effort to learn enough Japanese and German (albeit very little) to navigate those programs.

        Or to put that another way - If Bill Gates only spoke Italian, a LOT more people would have learned at least a basic proficiency in it by now.

    Simply define a strings table with two key fields. The first key defines the string ID, the second defines the language ID. The sole attribute would then be the string itself.


    Adding a new language then just becomes a case of adding a new language ID to the system, and adding a new string becomes adding a string ID.


    Any place that you want to generate an output string, simply insert a token which represents the string ID. Your translation code scans for the tokens, gets the current language from the environment, and then searches your strings table for the substitution string.


    (For those who remember the Commodore PET computer, this is very similar to how it worked. The Print command, for example, was stored internally as a "?" token. It substituted when displaying.)


    You do not need a table for the string IDs, an enumerated type would be sufficient to track what IDs are in use and what for. You WOULD want a table for the language, with the language ID as the key field (preferably as an enumerated type) and the font ID as the attribute. If you are not using fonts (eg: plain-text output) then again you can just use the enumerated type.


    Because you would NOT be encoding font data into the string (NEVER, EVER do that, by the way, as you're just padding the data with redundant information, and introducing extra complexity), you can replace the font at will, provided it conforms to the mapping standards for international character sets.

    • The way you've mentioned works fine if you are only going to display static strings, but if you wish to display dynamic strings you will need a different approach.

      Languages like English are SVO while other languages are SOV. Throw in a few extra grammar rules and a simple string substitution scheme becomes impossible because printf("%s %s %s", S, V, O); will simply not create correct strings for any language that uses a different ordering.
      • That's true, I hadn't considered that aspect. What you would need to do, in that case, is to store the ordering in the language table, then use that ordering to generate the SQL needed to pull the strings. Then you would be able to handle flexible ordering.

        Character direction is another problem, if you're going truly international, as some languages alternate between left-to-right and right-to-left on different lines. This is a problem, because you can't now just store a direction somewhere and use that t

        • Forget that. Just use a a substition with labels instead of sprintf-ing everything. Then you can have "Hello my name is $name." and "Guten Tag, Ich heisse $name." (Ok, ok in this instance it's the same order, but I'm having trouble of thinking of better examples and I am lazy and you get the idea and it makes way more sense than %s.) Just name the substitution arguments.

      Internationalization is the process of adapting your program so that it can easily be made to work in any locale. Not hardcoding strings in english, not assuming 1 byte == 1 char, that kind of thing. A good i18n architecture makes localization much easier.

  • I created a multilingual user interface for a moderately complicated web application with a small number of users like this:

    create an include directory 'lang' with language files for every language needed. In my case, two 'en.inc.php' for English and 'nl.inc.php' for Dutch. These files contain the strings for the interface in an associative array. Example:

    'nl.inc.php' contains:

    $l10n['ja'] = 'ja';

    'en.inc.php' contains:

    $l10n['ja'] = 'yes';

The way I understand the rule is that if your text in English takes up 65% of the space that you could use for text then you probably have enough room to place the translated text in that location for any other language.

        Of course this only makes sense for horizontal text and maybe even only left-to-right at that. It's also bound to be wildly off in some cases. The reasoning I h

  • It's a proportionality thing.. Often, the difficulty of programming i18n is less dramatic than the problem of actually generating all the different language sets.. Often such management means an advanced GUI (maybe not advanced, but certainly more than just raw field entries for a DB-backed widget).

    i18n is generally token language-set in a 1:n relationship.. Which maps nicely to table layouts, thus I don't see any need to create i18n support in the DB itself.

    I did this in 2003 for a CMS+ecommerse system I did for a company. You had Smarty [php.net] templates which had things like {productstr1} in them. The text strings were referenced by language and string ID, and if the string didn't have a specific version for your language it defaulted to English. This string was loaded from the database in a preparse plugin and was cached in a per-language directory. It worked ok, a bit kludgy but sufficient to get the job done.

  • From a database perspective, there's two basic ways to do this. Assuming you need to present an I18N version of a Widget table, you can:

    1. Define Widget and WidgetText, with all the I18N material moved to WidgetText. WidgetText is keyed on the Id from Widget and a Culture identifier. Every time you need a Widget, you JOIN to WidgetText based on the Id from Widget and the Culture identifier of the requesting user.

    2. Add a Culture identifier column to your Widget table, and use that in your WHERE clause

  • You may need to start by converting your iso-8859-1 or other European ASCII to UTF-8 or another sensible Unicode charset. Some of our MySQL data was in the dreaded windows-1252 encoding, and I had to convert it to UTF. I downloaded the Convert Charset class (found via http://phpclasses.org/ [phpclasses.org] from Mikoaj Jdrzejak [republika.pl], and with that I discovered I could basically convert anything I wanted from whatever charset to whichever charset I like. Wrote a couple scripts, and that was that.

  • Gettext and separate version. (Score:3, Insightful)

    Use gettext for general string i18n & l10n. Gettext is the defacto standard, it works, it's reasonably efficient, and there are many tools to support "unskilled" localisers to do the translating for you.

    For large or potentially dynamic text l10n (eg entire content of pages, descriptions of products in a database, etc etc..) then you need to have 1 version for each language you are supporting (you COULD do it through gettext but it would be rather tedious). How you do that is of course 100% dependant on your application.

  • might I suggest you browse various PHP OSS projects. Most of the biggest most popular packages have language selections. You're bound to find some good examples on how to handle i18n.

  • As a number of people have mentioned, Internationalization and localization can be an incredibly complex process.

    Since you are working with an existing system, you don't have the option of designing in I18N support from the very beginning.

    Get a good book.

    I recommend "XML Internationalization and Localization" by Yves Savourel, and "Beyond Borders web globalization strategies" by John Yunker. Both the authors have been in the I18N business a long time. They know what they are talking about.
