Furigana according to Wikipedia is:
A Japanese reading aid, consisting of smaller kana, or syllabic characters, printed next to a kanji (ideographic character) or other character to indicate its pronunciation. It is typically used to clarify rare, nonstandard or ambiguous readings, or in children's or learners' materials.
Simply put, you could know how to read a certain word in Japanese but that doesn't necessarily mean that you know how to pronounce it. To solve this problem, publishers use furigana to tell the reader how a particular word is pronounced.
A Japanese sentence looks like this:
林さんは英語は話せます。
To add a phonetic guide it is common practice to include the pronunciations between parenthesis right after the kanji, like this:
林（はやし）さんは英語（えいご）は話（はな）せます。
While this makes pronunciations very clear it makes the text less readable.
This module takes furigana entered in the above format and converts it to proper HTML using ruby, rb, rp, and rt tags. This will turn the above sentence into this:
<ruby><rb>林</rb><rp>(</rp><rt>はやし</rt><rp>)</rp></ruby>さんは<ruby><rb>英語</rb><rp>(</rp><rt>えいご</rt><rp>)</rp></ruby>は<ruby><rb>話</rb><rp>(</rp><rt>はな</rt><rp>)</rp></ruby>せます。
Supported browsers (like Chrome) will render it like this:
And a nice advantage is that browsers that don't support ruby text will degrade gracefully and render your text exactly as you entered it. Actually the text will look the same but since the furigana will now be wrapped in its own tags, you will be able to style them the way you want. You couldn't have done this without ruby tags. So as you see the ruby tag has its benefits.
You can install this module in different ways. The easiest one is by using composer. For this to work you need to add the module to your require section in the composer.json file:
"require": {
"jv/jvfurigana": "dev-master"
}
Then run: php composer.phar update
If you don't want to use composer, you can clone or download this repository into your ZF2 modules directory.
Whatever way you choose, don't forget to enable the module in your config/application.config.php file.
From within a view script, you can do:
<?=$this->jvfurigana('こんにちは世界（せかい）'); ?>The view helper needs to be initialized with a render strategy that implements the RenderStrategyInterface. By default it implements the FilterStrategy which will work fine with PHP 5.3. In some windows installs I noticed that this strategy was not catching all the furigana correctly. If that is your case, you can use the ManualStrategy which, as the name implies, does a lot of the work manually.
You should always use the FilterStrategy because it outperforms the ManualStrategy by far. Rendering 40 kilobytes of japanese text with FilterStrategy took 0.002 seconds while the ManualStrategy took 18.177 seconds on a MacBook Pro i7 with 16gb of ram.
