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

Although numFiles will change after overwriting a file, it will be back normal when you ZipArchive::close() and open() it again.
NULL indexes don't persist either. Only the new order is kept. So feel free to overwrite.

Here overwriting works the same as deleting and adding. So it's not necessary to ZipArchive::deleteName() first.

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.
