note 113154 added to ziparchive.deleteindex

I'm trying to delete file using deleteName and deleteIndex, it returns true but files are not removed. can anybody tell me how could it be? Here is code snippet $zip = new ZipArchive ; $zipname = "www.zip" ; chmod( $zipname, 0777 ) ; if ( $zip->open( $zipname ) ) { $loop = $zip->numFiles ; for ( $i = 0; $i < $loop; $i++ ) { var_dump($zip->deleteIndex( $i )) ; var_dump(deleteName($zip->getNameIndex( $i )). "/") ; } }$zip->close() ; ---- Server IP: 69.147.83.199 Probable Submitter: 182.189.7.164 ---- Manual Page -- http://php.net/manual/en/ziparchive.deleteindex.php Edit -- https://master.php.net/note/edit/113154 Del: integrated -- https://master.php.net/note/delete/113154/integrated Del: useless -- https://master.php.net/note/delete/113154/useless Del: bad code -- https://master.php.net/note/delete/113154/bad+code Del: spam -- https://master.php.net/note/delete/113154/spam Del: non-english -- https://master.php.net/note/delete/113154/non-english Del: in docs -- https://master.php.net/note/delete/113154/in+docs Del: other reasons-- https://master.php.net/note/delete/113154 Reject -- https://master.php.net/note/reject/113154 Search -- https://master.php.net/manage/user-notes.php
