Today, I will talk to you about the characteristics of twig, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

The characteristics of twig are: concise, template syntax, powerful, to provide all the functions needed to create a template, easy to learn, expansibility, after complete unit testing, enough stability, complete documentation, security, error tips, fast.

Characteristics of twig

Brevity

Compared to Twig, using PHP syntax in a template can be particularly tedious, especially when some processing of the output is required:

To achieve the same operation, Twig uses a more concise syntax and is more readable

{{var} {{var | escape}} {{var | e}} {# variable escape (escape) acronym #}

Templated grammar

Twig provides many shortcuts for common business logic, for example, when the traversal array may be empty, you can judge like this:

{% for user in users%} * {{user.name}} {% else%} No users have been found. {% endfor%}

Powerful function

Twig provides all the functions needed to create templates, such as multiple inheritance, content blocks, automatic escape of output, and so on.

{% extends "layout.html"%} {% block content%} Content of the page... {% endblock%}

Simple and easy to learn

The syntax of Twig has been greatly improved, which is very easy to learn, and users can quickly create templates with a little learning.

Expansibility

Developers can extend their tags, filters, and functions based on the framework provided by Twig to make Twig have a variety of simple or complex capabilities.

Unit testing

After complete unit testing, Twig is stable enough to have no problem even for large projects

Complete documentation

The documentation of Twig is complete, and the instructions and complete API documentation can be read online: https://twig.symfony.com/doc/1.x/

Safety

Escape escape: for security reasons, the code in the template needs to be escaped. Twig can provide automatic escape at the global or code block level

{% autoescape "html"%} {{var} {{var | raw}} {# var does not escape #} {{var | escape}} {# var will not repeat escape #} {% endautoescape%}

Sandboxie: Twig can execute any template in the sandboxie environment, so that users can only access some of the tags, filters or methods defined by the developer, thus making the program more secure. The sandboxie environment can be enabled globally or only for some templates.

{{include ('page.html', sandboxed = true)}}

Error prompt

When there is a syntax error in the template, Twig will provide very useful information, pointing out the file name and code location of the error, which provides convenience for development and debugging.

fast

One of the goals of Twig is that the sooner the better. Faster efficiency than traditional PHP code is achieved by compiling templates into optimized PHP code.
