Boiler is a small template engine for PHP 8.5+, inspired by Plates. Like Plates, it uses native PHP as its templating language rather than introducing a custom syntax.

Key differences from Plates:

- Automatic escaping of strings and [Stringable](https://www.php.net/manual/en/class.stringable.php) values for enhanced security
- Global template context, making all variables accessible throughout the template

Other highlights:

- Layouts, inserts/partials, and sections (with append/prepend)
- Optional HTML sanitization via `symfony/html-sanitizer`
- Custom template methods and optional whitelisting of trusted value classes

Installation
------------

[](#installation)

```
composer require duon/boiler
```

Documentation
-------------

[](#documentation)

Start here: `docs/index.md`.

Quick start
-----------

[](#quick-start)

Consider this example directory structure:

```
path
`-- to
	`-- templates
		`-- page.php

```

Create a template file at `/path/to/templates/page.php` with this content:

```
ID
```

Then initialize the `Engine` and render your template:

```
use Duon\Boiler\Engine;

$engine = Engine::create('/path/to/templates');
$html = $engine->render('page', ['id' => 13]);

assert($html == 'ID 13');
```

Common patterns
---------------

[](#common-patterns)

Render from multiple directories (optionally with namespaces):

```
$engine = Engine::create([
	'theme' => '/path/to/theme',
	'app' => '/path/to/templates',
]);

// Renders the first match (theme overrides app)
$engine->render('page');

// Force a specific namespace
$engine->render('app:page');
```

Control escaping:

```
$engine = Engine::create('/path/to/templates');
$engine->render('page');
$engine->renderUnescaped('page');

$engine = Engine::unescaped('/path/to/templates');
$engine->render('page');
$engine->renderEscaped('page');
```

Template helpers available via `$this` inside templates:

- `$this->layout('layout')`
- `$this->insert('partial', ['value' => '...'])`
- `$this->begin('name')` / `$this->append('name')` / `$this->prepend('name')` / `$this->end()`
- `$this->section('name', 'default')` / `$this->has('name')`
- `$this->raw($value)` when you need the original value for comparisons or custom logic
- `$this->esc($value)` and `$this->clean($html)`
