Microsoft Language translation is an interesting service. Not only can you do language translation, you can also detect the language of a particular text. The given class provides a PHP wrapper which will help developers translate text from one language to another in a easy manner. The library also supports caching, helping you keep your translations fast and simple.

His translation library requires an AppId for configuration and cURL to handle the messaging back and forth. Translation is as easy as calling "translate()" on a string, language fetching with "LanguageNames()" and even converting the text to speech with the "speak()" method.
