php anonymous function parameters

I'm trying to understand Anonymous Functions in php (laravel framework) , I searched about my basic question here but I didn't find the answer.

echo preg_replace_callback('~-([a-z])~', function ($match) {
    return strtoupper($match[1]);
}, 'hello-world');
// outputs helloWorld

What parameters gone inside the anonymous function ??

Route::match(['get', 'post'], '/', function () {
    return 'Hello World';
});

So it sends in the array of matches.
