Laravel oldstyle url or simple php file inside project

Hello, An api that i use wants url format which matches with this regex pattern

http[s]?://(([^/:.[:space:]]+(.[ ^/:.[:space:]]+)*)|([0-9](.[0- 9]{3})))(:[0- 9]+)?((/[^?#[:space:]]+)(?[^# [:space:]]+)?(#.+)?)? So if i have an address like this

domain.com/y i have to convert it to the

domain.com/index.php?something=y I am using laravel 5.1 and need to be change pretty url to the traditional format.

Is there a way to do this, or is there any option to use simple php page inside laravel project?
