We can remove a directory in PHP using the rmdir function. The
directory must be empty and permissions must allow its removal.
{{code:php rmdir('/path/to/dir_to_remove'); }}
Ruby's Dir class provides two class methods, Dir.delete and Dir.rmdir,
that are synonyms. Both are functionally equivalent to PHP's rmdir.
{{code:ruby # identical Dir.delete('/path/to/dir_to_remove') Dir.rmdir('/path/to/dir_to_remove') }}
One drawback of both PHP's rmdir and the class methods provided by Ruby's
Dir class is that directory must be empty before it can be removed.
You can remove a non-empty directory, in the same way as you would with rm -rf on the shell of a Unix-like system, by using FileUtils.rm_rf.
{{code:ruby require 'fileutils'
FileUtils.rm_rf('/path/to/dir_to_remove')
}}
