Translation

[thblckjkr]

I've been working in a simple approach to translate the web pages with the less effort possible.

The result, the following code. I hope you like it.

Use
The use it's pretty simple, in the PHP file to be translated, just include the file that acts as translator, and use the function lang()

include 'lang/translate.php'; //Include this at top
<?=lang('ANY TEXT')?> <!-- Translate "ANY TEXT" (HTML format) -->

The lang() function search the keyword on the language files, if no language file exist or the keyword is not found, the original text is returned, if the keyword and file are found, the translated phrase is returned. The current language it's selected by the $_SERVER['HTTP_ACCEPT_LANGUAGE'] directive.

The language files are in JSON format, to make possible the implementation (on a easy way) to JavaScript and another languages.

Only the index page was translated (To Spanish, because i'm Mexican). Just for testing, also the template.json will help to any translation. And the button of search is being displayed in Chinese (for Chinese users, also just for testing).

If you can give any kind of feedback i'll be happy.

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

There's zh-CN zh-TW zh-HK fr-CA fr-FR fr-BE en-US en-GB etc.
I'm not sure if there's major difference between fr-CA and fr-FR, but it definitely is different between zh-CN and zh-TW.
A better way to do this is parse Accept-Language, fallback to next one when a language doesn't exist.

My browser's header:

accept-language: en,en-US;q=0.9,zh-CN;q=0.8,zh;q=0.7

$lang = (isset($_GET['lang'])) ? $_GET['lang'] : $lang;
$lang_file = INCLUDE_PATH . '//lang/' . LANGUAGE . '.json';
$lang_file_content = file_get_contents($lang_file);

Also you may want to use string realpath ( string $path ) to check if $lang_file is still inside the lang directory, prevent someone request path like https://trace.moe/?lang=../../../../etc/passwd.
Although passwd definitely can not parsed by json parser, read arbitrary file is bad.

I think it's not a good idea to put html tags in object keys :\

I also wanted to translate pages like about.php and faq.php
It doesn't seems nice to me if we put those text in a big json and leave that page with a lot of placeholders.

Thanks for the feedback. In retrospective, I can see that the approach was not the best for the project. I will be working in a better way to do it. Thanks for your comments.
