Bug report #47752

var_dump(filter_var('-0',FILTER_VALIDATE_INT)); // bool(false) 
var_dump(-0); // int(0) 

In my opinion FILTER_VALIDATE_INT must work like var_dump(-0);
Sooner or later we will get problems if everything works different.

PHP defines -0 as an int. So FILTER_VALIDATE_INT must also accept -0 and +0.

Thank you
