Regex extract string after last point

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

example.doc -> .doc

another.example.jpeg -> .jpeg

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

$ext = pathinfo($path, PATHINFO_EXTENSION);

in fact, this could be resolved by using nearly dozen methods. strrpos() + substr(), pathinfo(), explode()+end() are examples.

Try this regular expression:

\.[^.]*$

You can try with following regex:

^.*(\..*)$
