PHP ZipArchive() creates corrupt zip file

I have upgraded the server and since found that my zip is no longer working.

I currently am using: Apache 2.2.22 , PHP 5.3.10

Configure Command
'./configure' '--disable-fileinfo' '--disable-pdo' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-magic-quotes' '--enable-mbstring' '--enable-sockets' '--enable-zip' '--prefix=/usr' '--with-curl=/opt/curlssl/' '--with-curlwrappers' '--with-freetype-dir=/usr' '--with-gd' '--with-gettext' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mysql=/usr' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--with-openssl=/usr' '--with-openssl-dir=/usr' '--with-pcre-regex=/opt/pcre' '--with-pic' '--with-png-dir=/usr' '--with-xpm-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr'


A simple script:

eg:
$zip = new ZipArchive();
$filename = "test112.zip";

if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
    exit("cannot open <$filename>\n");
}

$zip->addFile("Lighthouse.jpg","file1.jpg");
$zip->addFile("Penguins.jpg","file2.jpg");

echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();

------------
(using all: Windows 7 zip, WinZip, WinRAR)

The zip file opens and the filesize looks ok in the two files, but when I open the images, it says they are corrupt.

I have tried both ZipArchive and also pclZipLib... both work with the same results.

Thanks

I am also using PHP 5.3.10.  Here is my ZIP information:
Zip       enabled
Extension Version       $Id: php_zip.c 321634 2012-01-01 13:15:04Z felipe $
Zip version       1.9.1
Libzip version       0.9.0

If you will post the example files here I will be glad to try them on my server.

Using this code, I successfully Zipped up a directory full of GIF images.  Windows 7 could not open the Zip Archive, but it worked fine with WinRAR.
<?php // RAY_zip_archive.php
error_reporting(E_ALL);
date_default_timezone_set('America/New_York');

// THE URL ARGUMENT IS THE NAME OF THE DIRECTORY TO ZIP
$dir = (!empty($_GET["dir"])) ? $_GET["dir"] : NULL;

// BUT FOR MY TESTS IT IS HARDCODED
$dir = 'RAY_aslimages';

if (!$dir) die("PLEASE PROVIDE dir= IN THE URL");

// A GOOD PATH ON MY SERVER
$path
= getcwd()
. DIRECTORY_SEPARATOR
. $dir
;
if (!is_dir($path)) die("FAIL: NOT VALID PATH $path");

// THIS IS THE LIST OF scandir() RESPONSES THAT WE DO NOT WANT
$unwanted
= array
( '.'

;

// INSTANTIATE THE OBJECT
$zip = new ZipArchive();

// CREATE A DATE-TIME ARCHIVE NAME
$archive

. '_archive_'
. $dir
. '.zip'
;

// TRY TO CREATE THE ARCHIVE
if ($zip->open($archive, ZIPARCHIVE::CREATE)!==TRUE) die("FAIL: ZIP->OPEN <$archive>");

// GET THE LIST OF FILES
if (!$files = scandir($path))   die("FAIL: scandir() $path");
foreach ($files as $file)
{
    // SKIP THE UNWANTED AND ADD THE OTHERS TO THE ARCHIVE
    if ( in_array($file, $unwanted) )                    continue;
    if ( !is_file($path . DIRECTORY_SEPARATOR . $file) ) continue;
    $zip->addFile($path . DIRECTORY_SEPARATOR . $file );
}

if (!$zip->close()) die("FAIL: ZIP->CLOSE");

$fs  = filesize($archive);
$fsn = number_format($fs);


// PREPARE A LINK
$link
= '<a target="_blank" href="'
. $archive
. '">'
. "DOWNLOAD $archive $fsn BYTES"
. '</a>'
;
// echo $link;

// SEND THE ZIP ARCHIVE
header("Content-Type: archive/zip");
header("Content-Disposition: attachment; filename=$dir".".zip");
header("Content-Length: $fs");
readfile($archive);

Well Ray_Paseur, I have good news...

As I was getting the script and the images I was testing with, this EE uploader was failing them... upon closer look, the images were corrupt on the server... they originally were ftp'd from one server to the other and I guess I did not check the originals. (cant really believe that, but have no proof to the contrary)

Of course this was a small clip from a larger sript and I went back to the section of the script that moves the files in the first place... updated FTP_ASCII with FTI_BINARY and it worked.

...(ftp_fget($conn_id, $handle, $FilesMyrow["CurrentFileName"], FTP_BINARY, 0)...

Again, not sure why this would change on the new server... they have been ASCII for the last 2 years.

Let me know what you would like to do with points...

Thanks for your help!

Glad to hear that.  I tested with your image files and got the same result as before - WinRaR did a fine job.

Since it's not a ZIP related issue, I suggest you delete the question.  Not worried about the points - I have enough points to orbit Saturn.

All the best, ~Ray
