Description:
------------
I create an archive (.zip) with class ZipArchive, with four files into. 
And when I want to delete the last file, in this archive, the function deleteName() return true, but the file is not remove from the archive.
The three others files were correctly remove, but not the last.

Reproduce code:
---------------
---
From manual page: function.ziparchive-deletename
---

        private function myDelZipFile($p_sName){
            $l_oZip = new ZipArchive();                       
            if($l_oZip->open(RACCORDEMENT_ZIP_FILE_PATH . "/" . $_SESSION['step5']['zip_name'] . ".zip", ZIPARCHIVE::OVERWRITE) === true){
                $l_oZip->deleteName( $_SESSION['step5'][$p_sName . '_name']) === true;
                $l_oZip->close();                
                return true;
            }            
            return false;            
        }

Expected result:
----------------
The archive file ever contained the last file. 

Actual result:
--------------
The archive would be empty.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

<?php

$l_oZip = new ZipArchive();                       
if($l_oZip->open(RACCORDEMENT_ZIP_FILE_PATH . "/" . $_SESSION['step5']['zip_name'] . ".zip", ZIPARCHIVE::OVERWRITE) === true){
$l_oZip->deleteName( $_SESSION['step5'][$p_sName.'_name']);      $l_oZip->close();

Is that self-contained? I don't have your session available.
 [2009-12-01 09:15 UTC] c dot hugot at uniteam dot fr 
In the code $_SESSION['step5'][$p_sName . '_name'] is the name of the file, that is in the archive file ($_SESSION['step5']['zip_name'] . ".zip" = the name of the archive file), and RACCORDEMENT_ZIP_FILE_PATH is the constant, that contained the path to the archive file.

I hope, that could help you to solve my problem. Thanks for your work.

Best regards.

Please provide a script we can use to reproduce your problem, not only a function.

I found the cause of my problem, it provide of an error of my script.

The cause is the second argument passed to the method ZipArchive::open(), in my script it was ZIPARCHIVE::OVERWRITE. I suppress it and my script work correctly.

Sorry for my english, my useless bug reporting and the disarrangement.

Best regards,

Christophe HUGOT
