fclose

  • To close a file in PHP, you pass its stream resource to fclose.

    PHP

    $f = fopen('/path/to/foobar', 'w');
fwrite($f, 'chars');
fclose($f);

    Similarly, if you use Ruby’s File.open method to return a file instance, you need to call the close method on that instance.

    Ruby

    f = File.open('/path/to/foobar', 'w')
f.write 'chars'
f.close

    Alternatively, you can have Ruby automatically close files that you open by passing a block to the File.open method:

    Ruby

    File.open('/path/to/foobar', 'w') do |f|
  f.write 'chars'
end

    Using a block in this way is considered a best practice in Rails applications. For more on this, please see fopen.
