Validate PHP code examples in documentation.

This file describes version 2 which uses php8 attributes.

For version 1 which uses docblock style annotations see this link.

Why?

Did you update your library, but forgot to update code examples in README? Are your users complaining on syntax errors in your examples? Do you find it too cumbersome to manually test all examples? Readme-Tester lets you automate the process of validating PHP code examples in documentation files.

A simple example

Readme-Tester uses php8 style attributes inside HTML-comments (to make them invisible after rendering on for example github) to specify the expected result of a code example.

The following simple example asserts that the code outputs content.

<!--
#[ReadmeTester\ExpectOutput('/foo/')]
-->
```php
echo "foobar";
```
