I wrote some code.

I liked writing this:

```php
<?php

declare(strict_types=1);

class Foo
{
    public function __construct()
    {
        echo 'Foo class constructed';
    }
}
```
EOF;
        Article::create([
            'title' => 'Some code I did',
            'main' => $articleWithCode,
            'published' => 1,
        ]);
    }
}
