Internationalization (I18N) and Localization (L10N)

Many web application built with PHP will not have internationalization in mind when it was first written. It may be that it was not intended for use in languages and cultures. Internationalization is an important aspect due to the increase adoption of the Internet in many non-English speaking countries. The process of internationalization and localization will contain difficulties. Below are some general guidelines to internationalize an existing application.

The localize function searches for a translated string that matches original from your translation source.

Compound Messages

Compound Messages

Compound messages can contain variable data. For example, in the message "There are 12 users online.", the integer 12 may change depending on some data in your application. This is difficult to translate because the position of the variable data may be difference for different languages. In addition, different languages have their own rules for plurals (if any) and/or quantifiers. The following example can not be easily translated, because the sentence structure is fixed by hard coding the variable data within message.

TChoiceFormat

TChoiceFormat

Using the localize function or TTranslate component to translate messages does not inform the translator the cardinality of the data required to determine the correct plural structure to use. It only informs them that there is a variable data, the data could be anything. Thus, the translator will be unable to determine with respect to the substitution data the correct plural, language structure or phrase to use . E.g. in English, to translate the sentence, "There are {number} of apples.", the resulting translation should be different depending on the number of apples.
