PHP Glob所有目录中某些文件不存在

Question

I have directory that contains all projects: /projects/{project name}

Some projects contains checksum file (checksum.chk).

I can get all directories that contains checksum file with glob:

glob('/projects/*/checksum.chk')

Now I need list of all project that does NOT contains checksum file. Simply negating file name doesn't work.

glob('/projects/*/!(checksum.chk)') // doesn't work

This can be done with iterators or similar, but im looking for glob() solution if possible.
