Overviewor what will we talk about today?


Overview

• Internationalization (I18n)

What is translation about?

Creating and working with translation

Let’s view it

Future improvements

5 Overview


Internationalization (I18n)or one to rule them all ?


Generic overview – I18n vs L10n

• Internationalization versus Localization:

I18n => Support other regions without changing code

L10n => Adopt your project for a specific region

• Zend Framework supports them all

Not all people are native English!

7 Internationalization


Generic overview – What’s a locale

• Locale

Locale, the working horse for L10n

Language + Region

Region vs Country

Additional informations (charset, encoding)


en_US = english language + region USAde_AT = german language + region Austria


Zend Framework and I18n – Classes

• Zend_Locale

Locale handling (independend from PHP and OS)

Pre-translated informations

Formatting

How does translation work

• Languages are different

Provide your user with a language he understands

Most browsers send their wished languages

Translation is just one part to a multilingual site


User accessingSite

Detectlanguage

Selecttranslation

Settranslation


Source files – Adapters Concept

• Adapter concept

Multiple source types supported

Easy to implement own adapters

• Select your adapter based on your usage

Usage may grow… switching to other adapter is just 1 codeline



Source files – Adapters

Array

Csv

Gettext

Ini

Qt

Tbx

Tmx

Xliff

XmlTm

your own…



Source files – Array adapter

• Pro

Fast, Faster, Fastest

Human readable

return array(‘Original content’ => ‘Translated content’‘Another content’ => ‘Also translated’

);


• Con

No editor tools

Not customer friendly

• Usage

During development

Small to medium sites


Source files – CSV adapter

• ProFast

Human readable

Customer editable

“Original content”;”Translated content”“Another content”;“Also translated”


• Con

No creation tools

• Usage

Translations by customer



Source files – INI adapter

• Pro

Fast

Human readable

Original_content = “Translated content”Another_content = “Also translated”


• Con

No creation tools

Not customer friendly

Key limitations• Usage


Mixing translation with configuration


Source files – Gettext adapter

• ProEncrypted for customer

Free Tools

Professional translation

BINARY FORMAT (*.mo files)… *.po is NOT Gettext


• Con

Fixed for customers

Not human readable

• Usage

Small to enterprise sites

Many sources available


Source files – TMX adapter

• Pro

Professional translation tools

Supports HTML tags

** XML HEADERS **<tu tuid='Message 1'>

<tuv xml:lang="en"><seg>Message 1 (en)</seg></tuv><tuv xml:lang="fr"><seg>Message 1 (fr)</seg></tuv>

</tu>

Medium to Enterprise sites

HINT: TMX is said to be “Industry standard” butBEWARE it’s very huge & bloated format
