I am trying to get the last folder name from a path that i store in a string.
result = test
basename ( 'Home/new_folder/test' ); // output: test
As a side note to those who answered explode:
To get the trailing name component of a path you should use basename!
In case your path is something like
$str = "this/is/something/" the
end(explode($str)); combo will fail.
