Olyan mintha ezt írtam volna:

<code php>
app()->match('GET|HEAD', '/employees', "$controller@index");
app()->post('/employees', "$controller@store");
app()->match('GET|HEAD', '/employees/create', "$controller@create");
app()->match('POST|DELETE', '/employees/{id}/delete', "$controller@destroy");
app()->match('POST|PUT|PATCH', '/employees/{id}/edit', "$controller@update");
app()->match('GET|HEAD', '/employees/{id}/edit', "$controller@edit");
app()->match('GET|HEAD', '/employees/{id}', "$controller@show");

app()->run();
</code>
