Consider this example:



<?php

$zip = new ZipArchive;

$zip->open(...);



$zip->addFile('path/file', 'foo');

$zip->renameIndex(0, 'bar');



echo $zip->getNameIndex(0); // 'bar'



$zip->unchangeIndex(0);



echo $zip->getNameIndex(0); // 'false'

?>



Unless you call save() in between, the unchangeIndex() call reverts back to the initial state of the archive - where index '0' did not exist.



If you called save() after addFile() and then renamed the file, you would be able to revert/undo the name change.
