最后一个连字符后的Laravel路线

Say I have the following url:

/blog/this-is-a-post-20

and I want to separate it like this:

$urlTitle = "this-is-a-post";
$id = 20;

I'm currently trying the following:

Route::get('blog/{urlTitle}-{id}', function($urlTitle, $id)

But it's not working and it gives me:

$urlTitle = "this";
$id = "-is-a-post-20"

Route::get('blog/{urlTitle}-{id}', function($urlTitle, $id) {
    var_dump($urlTitle); // this-is-a-post
    var_dump($id);       // 20
})->where('urlTitle', '.*');

This will make urlTitle match the regular expression of 0+ characters. Expressions try to match as much as possible. That means it will first try to match this-is-a-post-20 and fail because the route can't continue to match -{id}. It "backtracks" until it can find the -{id} also.

To make this more efficient, replace the .* regex with .*(?=-) which will match 0+ characters followed by a -. This will reduce the number of times the regular expression engine needs to backtrack.
