Twig
Twig is a PHP template engine and compiled rendering library designed to separate business logic from presentation. It functions as a secure template language that generates HTML output by combining dynamic data with reusable layouts.
The system emphasizes security through a focus on preventing cross-site scripting attacks via automatic output escaping and content sanitization. To ensure execution efficiency, it compiles templates into optimized PHP code and utilizes a caching mechanism to bypass parsing on subsequent requests.
The engine provides comprehensive tools for template composition, including block-based inheritance and modular UI development. It includes capabilities for data transformation through filters, template control logic for conditional branching and loops, and helper functions for dynamic content generation.
Features
- HTML Template Renderers - Functions as a server-side engine that merges data with templates to generate dynamic HTML output.
- PHP Code Generators - Translates parsed template structures into native PHP classes for high-performance server-side execution.
- Rendered Content Sanitization - Prevents XSS attacks by sanitizing data and escaping content during the template rendering process.
- Output Escaping - Provides automatic escaping of dynamic content to protect web applications from cross-site scripting attacks.
- Modular UI Components - Enables the creation of reusable UI fragments and components that can be shared across different views.
- Reusable Components - Provides the ability to define and reuse modular UI components and layout fragments across different pages.
- Templating Engines - Provides a flexible and secure templating engine to separate business logic from the presentation layer in PHP.
- Block-Based Inheritance - Supports hierarchical layout organization through block-based inheritance, allowing child templates to override specific sections of a parent.
- HTML Content Renderers - Generates HTML output by combining dynamic data with reusable layouts, blocks, and modular components.
- Template Inheritance Systems - Provides a system for organizing website layouts through template inheritance, blocks, and nesting.
- Template Logic - Provides conditional logic, loops, and variable assignments to dynamically control the rendered output.
- PHP Compiled Libraries - Compiles templates into optimized PHP code to increase execution speed and reduce server overhead.
- Template Helpers - Supports built-in and custom helper functions to calculate values and format data during the rendering process.
- Compiled Caches - Caches compiled PHP templates on disk to bypass the parsing phase on subsequent requests.
- Tokenizers - Uses a lexer to break template strings into a stream of tokens based on regular expressions.
- Security-Hardened Languages - Implements a template language specifically designed with automatic output escaping to protect against XSS.
- Abstract Syntax Tree Parsing - Implements a parser that converts template strings into an abstract syntax tree for logic analysis before compilation.
- Content Format Transformers - Transforms raw data into human-readable strings using specialized filters for dates, numbers, and text.
- Data Transformation Filters - Offers a system of filters to transform and format raw data variables before they are rendered in the output.
- State Validation - Implements logical tests within templates to check variables for emptiness, types, or specific values.
