Route Parameters setting problem

Hi, I had a problem about the route parameters in Lumen.

My code is

$app->get('/a/{p1}/b/{p2}', function ($p3, $p2) use ($app) {
    return [$p3, $p2];
});

when I request it by curl -XGET http://localhost:8000/a/1/b/2

It print ["2","1"] not my expect result ["1","2"]

but the code rewrite to

$app->get('/a/{p1}/b/{p2}', function ($p1, $p2) use ($app) {
    return [$p1, $p2];
});

It print ["1","2"], that's my expect result.

I don't know why. Is there any reason for this?

Level 3

The injection of parameters is upon the names of it, you have to put the same name of parameter on the function and the string of route.

Level 1

But I think it should throw the error when the name of parameter on the function or controller function is different to route setting.

In my real case

route setting is /company/{company_id}/search/{keyword}

controller function parameter is function($companyId, $keyword)

the $keyword turn into {company_id}, it trapped me all day :(
