phpcd.vim: Infinite loop when create a buffer for a new file in a directory .

Hello lvht,

If you create a buffer for a new file in a directory that doesn’t exist, the phpcd#GetRoot() function will fall into an infinite loop.

For example, in the project root(with no .phpcd.vim), if I do vi foo/test.php (dir foo does not exist) and expand("%:p:h") seems to return foo.

Kind regards.
