$ _SERVER ['PHP_SELF']返回什么？ 在Laravel中获得奇怪的行为

I am using Lemp. This code

$url = $_SERVER['PHP_SELF'];

$url is set to the value www.mydomain.com/controller/action.

This is what I expected, since it is the url that the code is being executed.

but this

$pagina = $i + 1;
$url = $_SERVER['PHP_SELF'];
$url .= "/{$pagina}" ;

I get $url set to www.mydomain.com.br/1

My controller and action part of url are gone.

Isn't $_SERVER['PHP_SELF'] a constant.

I forgot to say my intention, I want to get the current url concanate a value that will be used as route parameter: wwww.mydomain.com.br/controller/action/my_route_parameter_concatenated

If I'm understanding your question correctly, you could use the url() helper function for this:

url('controller/action/my_route_parameter_concatenated')

https://laravel.com/docs/5.3/helpers#method-url

Hope this helps!

because Yo're using Laravel then maybe use framework power? http://blog.netgloo.com/2015/07/15/lumen-get-the-full-url-with-the-query-string/ Laravel Request has many more useful tools.

Answers and commments led me to the right direction. Since was going to use $url to create an anchor tag, I just used link_to_route('paineldecontrole.anuncios', $pagina, [ $pagina]).
