And under Windows that would be:
$ [PHPDOC_FOLDER]\bin\phpdoc.bat
In my bin folder was no bat file.
just phpdoc - 762 bytes - no file extension
At the command shell I can run it with php phpdoc
Collecting files .. OK
Initializing parser .. OK
Parsing files
[Exception]
No parsable files were found, did you specify any using the -f or -d parameter?
project:run [-t|--target[="..."]] [--cache-folder[="..."]] [-f|--filename[="..."]] [-d|--directory[="..."]]
[--encoding[="..."]] [-e|--extensions[="..."]] [-i|--ignore[="..."]] [--ignore-tags[="..."]] [--hidden] [--ignore-symlinks] [-m|--markers[="..."]]
[--title[="..."]] [--force] [--validate] [--visibility[="..."]] [--defaultpackagename[="..."]] [--sourcecode] [-p|--progressbar] [--template[="..."]] [--parseprivate] [--log[="..."]]
Maybe one could include a parameter --version and return the content of file ../VERSION
Now, let me find out - if it can actually do something
Maybe at the homepage https://www.phpdoc.org/ one could point to instructions for Installation for Windows
