Answer 1

pathinfo just parses a path, you can't use it in this context, when path doesn't have extension in it. You need to assign extension based on mime type.

So, first, get mime type, like here: https://stackoverflow.com/a/12023961/1059672 Then, assign extension based on mime type, like here: https://stackoverflow.com/a/16511092/1059672
