Twig is one of the most popular open-source template engines for PHP language, whose primary task is to separate the presentation layer of the application from the business logic. It provides a kind of library system that allows you to process input data and get HTML code based on it. It has a concise, accessible and easy-to-learn syntax, so that not only back-end, but also front-end developers can use it without any time-consuming prior preparation.

Twig - a secure and flexible template engine for PHP

Twig, first of all, allows you to create flexible and easily scalable projects based on concise templates that are extremely clear and readable. These templates have a syntax similar to regular HTML, so their code is easier to compile into PHP code, and the sheer load compared to regular PHP code is reduced to a minimum. This translates into tremendous speed and efficiency for the project and the developers themselves. Twig is also extremely flexible, as its open architecture allows you to easily add new custom features, filters, tags or keywords, and even your own syntax. What's more, this template engine provides great security for the entire project thanks to, among other things, Sandbox mode, which catches and automatically changes untrusted template code globally for the project. It also makes debugging the code easier, because whenever there is an error in the syntax, the template engine immediately displays a message with the name of the file and the line number where the error occurred. Twig also allows you to significantly reduce the weight of the entire project, since it allows you to create universal layouts and inherit them after defining specific blocks that can be used elsewhere in the project.
