Globalize your Web Applications: PHP's Locale Package [con't]
The PHP I18N Libraries
PHP comes with a set of PEARs that support internationalization from several
different angles and levels of complexity. PEAR stands for PHP Extension and
Application Repository, which is a framework and distribution system for
reusable PHP components. The package is named using the abbreviation for Internationalization
that we saw above. The
I18N library comes with the following class trees:
Root class I18N_Common I18N_Common I18N_Country I18N_Language Root class I18N_Format I18N_Format I18N_DateTime I18N_Number I18N_Currency
The following section covers each class in more detail.
I18N_Country class has a couple of functions to help determine the country
name from a country code:
- void getName([: $code = '']): Returns the name of the country
using the country code passed by the string argument
- void isValidCode(mixed $code): Check whether the country
code passed by the
$codeargument is valid.
I18N_Language class also implements the
void getName([: $code = ''], : 1)
It returns the name of the language using the language code passed by the string
1 parameter represents the string language code.
Here's a simple script that uses the
I18N_Language class to display an HTML-formatted
list of several languages:
The above code produces the following in a browser:
- en: English
- fr: French
- es: Spanish
- af: Afrikaans
- da: Danish
- de: German
That brings us to the end of part 1. In the next installment, we'll conclude
our look at PHP
I18N package and move on to our next language.
