Question

im trying to extract every file extension of an uploaded file.
For example:

example.doc -> .doc

another.example.jpeg -> .jpeg

even.anaother.example.pdf -> .pdf

i know this could be resolved by using regex, but regex are a closed book to me. So i need your help 🙁 please

thanks in advance!

Answer 1

Alternatively, don’t do regex but use a built-in: pathinfo()

$ext = pathinfo($path, PATHINFO_EXTENSION);
