Although this function displaces files of the same name, in actual fact, the original file is blanked and a new entry is added. The numFiles property is incremented.

Example:

File 1: foo
File 2: bar

$zip->addFromString('foo', 'new foo');

File 1:
File 2: bar
File 3: foo

if you try:

<?php
$zip->open("file", ZipArchive::CREATE);
$zip->addFromString("russian_letters/options.xml");
?>

wrong directory will be created.

if you try:

<?php
$zip->addEmptyDir("russian_letters");
?>

All be fine.

Note that this function overwrites existing files of the same name.
