How to Create a Twig Template in March 2025?

Twig has long been considered one of the most robust and flexible templating engines for PHP developers. As we step into 2025, creating a Twig template involves understanding the intricacies of newer updates while maintaining compatibility with legacy systems. This guide will walk you through the process of creating a Twig template, ensuring you’re leveraging the best practices and staying up to date with the latest features.

Setting Up Twig

Step 1: Install Twig

To begin building Twig templates, you need to have Twig installed. If you’re starting a new project, use Composer, which is the recommended package manager for PHP. Run the following command in your terminal:

1	composer require "twig/twig:^3.0"

This will add Twig to your project’s dependencies, ensuring you get the latest stable version. As of 2025, Twig 3.x is widely supported and provides numerous performance improvements.

Step 2: Create the Twig Environment

The Twig environment acts as a sandbox for your templates, managing how they are loaded and rendered. Initialize the environment in your PHP script like so:

require_once '/path/to/vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
$twig = new \Twig\Environment($loader, [
    'cache' => '/path/to/compilation_cache',
]);

Ensure you adjust the paths /path/to/templates and /path/to/compilation_cache to match your project’s directory structure.

Designing Your Template

Step 3: Template Syntax Basics

Twig’s syntax is intuitive and clean, emphasizing a separation between logic and presentation. Within a Twig template, you’ll mainly work with variables, filters, and control structures.

Here’s a simple example of a Twig template:

<!DOCTYPE html>
<html>
<head>
    <title>{{ title }}</title>
</head>
<body>
    <h1>{{ heading }}</h1>
    <p>{{ content }}</p>
</body>
</html>

In this template: - {{ title }}, {{ heading }}, and {{ content }} are placeholders for variables passed into the template context. - Twig syntax ensures that no PHP is mixed with your HTML, promoting a clean, maintainable codebase.

Step 4: Rendering the Template

To render a Twig template within your PHP script, use the following method:

1	echo $twig->render('template.html', ['title' => 'Welcome', 'heading' => 'Hello, World!', 'content' => 'This is a Twig template.']);

Replace 'template.html' with the path to your template file relative to the template directory.
