hello everyone, i am having a problem about my php code which tells that it cannot open a stream from function file(), and says 404 not found, true, but i already have filtered it but the error really comes out, but when i enter a valid id number, it produces no errors(ofcourse). What help am I going to need in solving this problem? To make it more understandable, I will give an example of the error message. (I am using XAMPP, and I still haven't uploaded it to any webhosting sites, this php file is still on my desktop. Nevermind the database connection and data insertion, it will still work without it.
