PHP Building Websites with PHP Slim Basics & Twig Templates Including & Rendering

Using rewrite rules with get and rendering

Just wondering since we use this to get a value within the string when we load the page

$app->get('/hello/:name', function ($name) {
    echo "Hello, $name";
});

How could could we set get variables in a link like this below and change it to something like cars/100

<a href="cars?id=100">Link</a>

so using the slim framework we could easily just retrieve the value from the cars page like so

$app->get('/cars/:id', function ($id) {
    echo "You've chosen, $id";
});

was maybe hoping someone could offer some insight or if i'm going the wrong way about it was thinking we'd might have to use rewrite rules but i have no idea about writing them

If you're in control of how the link is printed, could you not do something like this?

<a href="cars/100">Link</a>

That's possible, but more in-depth than what has been covered thus far. That's where Twig comes in, which takes the variables passed in by Slim from the route and binds them to parameters in your output.
