chdir

  • The chdir function in PHP changes the current working directory.

    PHP

    chdir('/path/to/foo');

    Ruby’s Dir.chdir is equivalent.

    Ruby

    Dir.chdir('/path/to/foo')

    Temporarily Changing the Directory

    Often times, you’ll want to change to a directory to perform some operations and then return to the directory you started from. In PHP, you can do this by storing the current working directory in a variable before calling chdir.

    PHP

    $start = getcwd();
chdir('/path/to/foo');
// perform some operations
chdir($start);

    Ruby’s blocks provide a convenient shortcut. If you pass a block to Dir.chdir, the directory will be changed before yielding to the block and then original working directory restored when the block exits.

    Ruby

    Dir.chdir('/path/to/foo') do
  # perform some operations
end
