Facebook FBT: PHP Internationalization Framework


FBT is an internationalization framework for PHP designed to be not just powerful and flexible, but also simple and intuitive. It helps with the following:

  • Organizing your source text for translation
  • Composing grammatically correct translatable UI
  • Eliminating verbose boilerplate for generating UI

This library is based on the JavaScript implementation of Facebook's FBT.



  • PHP 7.0 or higher
  • Composer is required for installation


composer require richarddobron/fbt

How FBT works

FBT works by transforming your <fbt> and fbt(...) constructs via Simple HTML DOM Parser. This library serve to extract strings from source and lookup translated payloads generated while execution. FBT creates tables of all possible variations for the given fbt phrase and accesses this at runtime.

Virus note: All files are scanned once-a-day by SourceCodester.com for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
