mkdir

• PHP’s mkdir function is used to create a new directory. An optional second argument specifies the permissions on the directory.

  PHP

  mkdir('/path/to/new_dir', 0700);

  Ruby’s Dir.mkdir class method works exactly the same way. Like PHP’s mkdir, it also accepts an optional second argument for permissions.

  Ruby

  Dir.mkdir('/path/to/new_dir', 0700)

  One nice feature of the mkdir function in PHP is that it supports an optional third argument, $recursive, that will recursively build directories like mkdir -p on the shell of Unix-like systems.

  PHP

  mkdir('/path/to/new_dir', 0700, true);

  Ruby’s Dir.mkdir doesn’t have a recursive mode. However, you can use FileUtils from the Ruby Standard Library to make a directory (FileUtils.mkdir) and recursively make a directory (FileUtils.mkdir_p).

  Ruby

  require 'fileutils'
   
  # make a directory
  FileUtils.mkdir('/path/to/new_dir')
   
  # recursively make a directory
  FileUtils.mkdir_p('/path/to/new_dir)
  

  Both FileUtils.mkdir and FileUtils.mkdir_p allow permissions to be optionally specified by supplying an options hash.

  Ruby

  require 'fileutils'
   
  FileUtils.mkdir_p('/path/to/new_dir', :mode => 0700)
