For examples, You can upload profile avatar to your profile. I want to remove the previous one the user had.
So before the query, where it changes the column "avatar" with the newfile2.jpg i would like to get the old file newfile1.jpg, and remove the previous image from the server.
How can I remove an image from the server?
You could just use a naming convention. Something like:
so when the user uploads the new avatar image it just overwrites the old one.
