How can I manipulate input values? about simple-php-router HOT 1 OPEN

You are not supposed to change super global variables, they contain values parsed and specific to the the request so that is not supported. If you need to manipulate the values and use them later on in your code, you should move them to your own custom variables. The request helper class supports custom variables and is available on everywhere, so you could always take advantage of that:

request()->stock = input('stockStatus', 0);

request()->stock // equals 0
