Twig is a modern PHP template engine features for flexible, fast and secure. It complies templates down to plain optimized PHP code, it also has a sandbox mode to evaluated untrusted template code, which allows Twig to be used as a template language for applications where users may modify the template design. Twig is powered by a flexible lexer and parser, which allows the developers to define its own custom tags and filters and create its own DSL.

Features of Twig:
- Template oriented syntax: Twig has shortcuts for common patterns, like having a default text displayed when you iterate over an empty array:
- Unit tested: Twig is fully unit-tested. The library is stable and ready to be used in large projects.
- Clean Error Messages: Whenever you have a syntax problem within a template, Twig outputs a helpful message with the filename and the line number where the problem occurred. It eases the debugging a lot.
- And much more.

Requirements:
- PHP 5.2.4 or Higher
