# Code Snippet

HTML: [altophp.com/code-snippet](https://altophp.com/code-snippet/)

Code Snippet stores code, original line numbers, selections, and annotations as
immutable values. Use it to pass an excerpt between extraction, analysis, and
presentation without tying the data to a renderer.

```php
use Alto\Code\Snippet\CodeSnippet;

$snippet = CodeSnippet::fromCode("first\nsecond\nthird", 'php', startLine: 24)
    ->selectLines(3);

echo $snippet->lines()[2]->number; // 26
```
