BabelKit is an interface to a universal multilingual database code table. It takes all of the programming work out of maintaining multiple database code definition sets in multiple languages. The code administration and translation page lets developers define new virtual code tables, new languages, enter all codes and their descriptions, and then translate them into all languages of interest. Perl and PHP classes retrieve the code descriptions and automatically generate HTML code selection elements in the user's language. This makes internationalization and localization of Web sites and database interfaces much easier.
EGroupware is a Web-based groupware suite. It contains many modules, including Calendar (personal calendar and group scheduling, notifications and alarms), Mail (IMAP only), InfoLog (todos, notes, and phone calls linked to contacts/CRM), Contacts (an address book for storing and sharing contact information), ProjectManager, Tracker (bug or incident tracking), TimeSheet, SyncML, CalDAV & CardDAV support, and SiteMgr content management
PHP Net_IDNA is a class to convert between the Punycode and Unicode formats. Punycode is a standard described in RFC 3492 and part of IDNA (Internationalizing Domain Names in Applications [RFC3490]) . This class allows PHP scripts to convert these domain names without having one of the PHP extensions installed. It supports both IDNA 2003 and IDNA 2008.
Konjugator helps with learning or interpreting verb forms in Welsh. It produces a list of around 200,000 inflected verb forms for almost 4,000 Welsh verbs, along with English glosses and parsing information. It attempts to conjugate Welsh verbs that are unknown to it, and will give parsing details for random Welsh verb forms if these are known to it.
I18N is a class that gets translation texts from flat files or from an SQL database. The system supports variables in translated strings and has a conversion facility to move data from one container to another. An included tool checks programs against sets of translated strings to detect references without strings or unused strings. Each call checks that referenced variables exist.
Expose is a PHP template engine. It supports server and client-sided caching, a plugin system (to simplify common tasks like inserting a date picker) and internationalization (to write templates in multiple languages using external translation files). Unlike most template engines, Expose's template script language is based on PHP itself, which means you don't have to learn a new syntax. You can use most of the PHP language elements and functions in the way with which you're familiar.
PEAR Validate is a set of useful methods to validate various kinds of data. It supports numbers (min/max, decimal, or not), email addresses (syntax, domain check, RFC 822), strings (alpha, upper and/or lowercase, numeric), dates (min, max), URIs (RFC 2396), and more. It also has many locale validation rules, specialized for each country or region (US, FR, UK, DE) or application domain (such as finance).
