I've needed a simple php class to manipulate zip files without PCEL extension, after reading all comment and tested 2 nice classes, here's my conclusion:
"You can use PHPMyAdmin's zip.lib"
-- Lennart Poot -- 12-Jul-2006 07:33
true, getting it is a bit awkward but the class is straight foward and works. BUT it only create zip files, it wont extract them.
"Hey guys, maybe you should check this out:
http://www.phpconcept.net/pclzip/index.en.php "
-- master_auer at web dot de -- 16-Nov-2003 07:49
true, check it if you need more advanced feature, this class is awsome.
CLXXXV. Zip File Functions
Introduction
This extension enables you to transparently read or write ZIP compressed archives and the files inside them.
Requirements
The bundled PHP 4 version requires » ZZIPlib, by Guido Draheim, version 0.10.6 or later
This extension uses the functions of » zlib by Jean-loup Gailly and Mark Adler.
Installation
Note: Zip support before PHP 4.1.0 is experimental.
Warning
Because the PHP 4 zip extension is unmaintained we recommend that the PECL extension is used rather than the bundled one.
In order to use these functions you must compile PHP with zip support by using the --with-zip[=DIR] configure option, where [DIR] is the prefix of the » ZZIPlib library install.
In order to use these functions you must compile PHP with zip support by using the --enable-zip configure option.
Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » http://pecl.php.net/package/zip.
You may download this PECL extension DLL from the » PHP Downloads page or at » http://snaps.php.net/.
In PHP 4 this DLL resides in the extensions/ directory within the PHP Windows binaries download.
Runtime Configuration
This extension has no configuration directives defined in php.ini.
Resource Types
There are two resource types used in the Zip module. The first one is the Zip directory for the Zip archive, the second Zip Entry for the archive entries.
Predefined Constants
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
ZipArchive uses class constants. There is three types of constants, Flags (FL_) errors (ER_) or mode (no prefix).
- ZIPARCHIVE::CREATE (integer)
- Create the archive if it does not exist.
- ZIPARCHIVE::OVERWRITE (integer)
- Always start a new archive, this mode will overwrite the file if it already exists.

Examples
Example 2553. Create a Zip archive
<?php
$zip = new ZipArchive();
$filename = "./test112.zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
?>
Example 2554. Dump the archive details and listing
<?php
$za = new ZipArchive();
$za->open('test_with_comment.zip');
print_r($za);
var_dump($za);
echo "numFiles: " . $za->numFiles . "\n";
echo "status: " . $za->status . "\n";
echo "statusSys: " . $za->statusSys . "\n";
echo "filename: " . $za->filename . "\n";
echo "comment: " . $za->comment . "\n";
for ($i=0; $i<$za->numFiles;$i++) {
echo "index: $i\n";
print_r($za->statIndex($i));
}
echo "numFile:" . $za->numFiles . "\n";
?>
Example 2555. Zip stream wrapper, read an OpenOffice meta info
<?php
$reader = new XMLReader();
$reader->open('zip://' . dirname(__FILE__) . '/test.odt#meta.xml');
$odt_meta = array();
while ($reader->read()) {
if ($reader->nodeType == XMLREADER::ELEMENT) {
$elm = $reader->name;
} else {
if ($reader->nodeType == XMLREADER::END_ELEMENT && $reader->name == 'office:meta') {
break;
}
if (!trim($reader->value)) {
continue;
}
$odt_meta[$elm] = $reader->value;
}
}
print_r($odt_meta);
?>
This example uses the old API (PHP 4), it opens a ZIP file archive, reads each file in the archive and prints out its contents. The test2.zip archive used in this example is one of the test archives in the ZZIPlib source distribution.
Example 2556. Zip Usage Example
<?php
$zip = zip_open("/tmp/test2.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
echo "Name: " . zip_entry_name($zip_entry) . "\n";
echo "Actual Filesize: " . zip_entry_filesize($zip_entry) . "\n";
echo "Compressed Size: " . zip_entry_compressedsize($zip_entry) . "\n";
echo "Compression Method: " . zip_entry_compressionmethod($zip_entry) . "\n";
if (zip_entry_open($zip, $zip_entry, "r")) {
echo "File Contents:\n";
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
echo "$buf\n";
zip_entry_close($zip_entry);
}
echo "\n";
}
zip_close($zip);
}
?>

This will simply unpack (including directories) $zip to $dir -- in this example the zip is being uploaded.
<?php
$dir = 'C:\\reports-temp\\';
$zip = zip_open($_FILES['report_zip']['tmp_name']);
while($zip_entry = zip_read($zip)) {
$entry = zip_entry_open($zip,$zip_entry);
$filename = zip_entry_name($zip_entry);
$target_dir = $dir.substr($filename,0,strrpos($filename,'/'));
$filesize = zip_entry_filesize($zip_entry);
if (is_dir($target_dir) || mkdir($target_dir)) {
if ($filesize > 0) {
$contents = zip_entry_read($zip_entry, $filesize);
file_put_contents($dir.$filename,$contents);
}
}
}

Notes from phpContrib [ a t ] eSurfers D o t COM are a ROCK!!!
1) In order to make it work U'll probably need:
** Allow Apache service to interact with desktop, but in that case U will notice momentarely console window opens and closes. That's may be annoying. The elegant solution instead of allowing interaction is redirect the command to some temporary file, and get rid of it later on:
define('UNZIP_CMD','unzip -o @_SRC_@ -x -d
@_DST_@ > tmpfile.txt');
2) I would recommend to use 7-zip, it's free and completely relyable. Also, it's comes with stand alone console executable which makes it quite convenient to place it in some exec library folder within your source, and refferering directly to it.
define("UNZIP_CMD","7za.exe x @_SRC_@ -o@_DST_@ > tmpfile.txt");

Previous poster's code is not using escape_shell_arg(), so it can be a huge security hole if attacker could manipulate filename/dir. I suggest replacing str_replace() with sprintf() and escape_shell_arg().

1) A warning to all users of PHP Zipping/Unzipping Classes: most of them require the whole content of the ZIP file and/or the unzipped contents to stay in memory. They work very well, but might fail with very large files. Keep this in mind before starting development of a project involving large ZIP files.
2) If all you need is to unzip files to a folder, and your server has a zip command line tool, all you might need is a function like this:
if(!defined('UNZIP_CMD')) define('UNZIP_CMD','unzip -o @_SRC_@ -x -d
@_DST_@');
function UnzipAllFiles($zipFile,$zipDir) {
$unzipCmd=UNZIP_CMD;
$unzipCmd=str_replace('@_SRC_@',$zipFile,$unzipCmd);
$unzipCmd=str_replace('@_DST_@',$zipDir,$unzipCmd);
$res=-1; // any nonzero value
$UnusedArrayResult=array();
$UnusedStringResult=exec($unzipCmd,$UnusedArrayResult,$res);
return ($res==0);
}
// * * * You DO NOT NEED the ZIP lib or M-ZIP to use this, but you will need the tool M-ZIP uses (unzip.exe or unzip for linux). * * *
// Use it this way:
$zipFile='/path/to/uploaded_file.zip';
$whereToUnzip='/path/to/writable/folder/';
$result=UnzipAllFiles($zipFile,$whereToUnzip);
if($result===FALSE) echo('FAILED');
else echo('SUCCESS');
By changing UNZIP_CMD (the same constant as in the m-zip lib) you can
of course untar, unarc, unrar, etc... provided you have the correct
unwhatever command or unwhatever.exe executable and write its correct syntax in UNZIP_CMD.
To see details of what tools you need and where to put them (or to use a syntax compatible to the standard zip lib) see http://eSurfers.com/m-zip/

You can use PHPMyAdmin's zip.lib library. It's available in the package PHPMyAdmin ( http://www.phpmyadmin.net/ ).
The zip class is located in /libraries/zip.lib.php
Next example generates a file named 'subfolder_in_zip_archive/_settings.php' using information of variable $settings. All files in folder 'folder_holding_files_to_add_to_zip' ($ad_dir) will be added to the archive as well.
In this example the raw zip archive data is responded to the browser. Uncomment the lines after 'write the file to disk' if you would like the archive to be stored on disk.
The function $zipfile -> addFile requires two parameters.
- The first parameter holds raw data and needs to be escaped using php function ‘stripcslashes’
- The second parameter holds the filename in the archive. You can enter complete paths to create complex folder structures
A timestamp can be added using the third additional parameter.
Regars,
Lennart Poot
<?php
require_once('zip.lib.php');
$zipfilename = 'zip_archive_to_generate.zip';
$zip_subfolder = 'subfolder_in_zip_archive';
$settings = '
<?php
$setting1 = "'.$setting1.'";
$setting2 = "'.$setting2.'";
?>
';
$ad_dir = 'folder_holding_files_to_add_to_zip';
// form is posted, handle it
$zipfile = new zipfile();
// generate _settings into zip file
$zipfile ->addFile( stripcslashes( $settings ), $zip_subfolder . '/_settings.php' );
if ($handle = opendir($ad_dir)) {
while (false !== ($file = readdir($handle))) {
if (!is_dir($file) && $file != "." && $file != ".." ) {
$f_tmp = @fopen( $ad_dir . '/' . $file, 'r');
if($f_tmp){
$dump_buffer=fread( $f_tmp, filesize($ad_dir . '/' . $file));
$zipfile -> addFile($dump_buffer, $zip_subfolder . '/' . $file);
fclose( $f_tmp );
}
}
}
$dump_buffer = $zipfile -> file();
// write the file to disk:
/*
$file_pointer = fopen('newzip.zip', 'w');
if($file_pointer){
fwrite( $file_pointer, $dump_buffer, strlen($dump_buffer) );

I needed a quick way to make a zip file from an entire directory including subdirectories. This is downright rough but if someone would fancy it up a bit it works good with the zip class at http://smiledsoft.com/demos/phpzip/ (free version).
Basic use in script would be...
make_archive("the/directory", $zip_archive_object);
<?php
function make_archive( $dir , &$zip, $extdir="")
{
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false ) {
if( $file != "." && $file != ".." )
{
if( is_dir( $dir . $file ) )
{
$zip->add_file($dir.$file,$extdir.$file);
make_archive($dir.$file."/" , $zip, $extdir.$file."/");
}
else
{
$zip->add_file($dir.$file,$extdir.$file);
}
}
}
closedir($dh);
}
}
return true;

i try to find function that will show exists file in zip archive or not. of course i not found it. and so write mine:
first will just check archive for list of files, if not found all files function return FALSE:
function zipx_entries_exists()
{
$names=array();
$args=func_get_args();
$far_size=count($args);
if($args[0])
{
for(; $zip_entry=zip_read($args[0]); $names[]= zip_entry_name($zip_entry));
for($x=1; $x<=$far_size; $t+=in_array($args[$x], $names), $x++);
return $t==--$far_size;
}else{
return 'No zip file in descriptor!';
}
}
example:
$zip=zip_open('any_zip_file_zip');
var_dump(zip_entries_exists($zip, 'photo_1.jpg', 'photo_2.jpg'));
second function will try to find files in zip, if not found it return string with names of not found files with specified delimeter:
function zipx_entries_nonexists_list()
{
$names=array();
$args=func_get_args();
$m=NULL;
$far_size=count($args);
if($args[0])
{
for(; $zip_entry=zip_read($args[0]); $names[]= zip_entry_name($zip_entry));
for($x=2; $x<=$far_size; $m.=(in_array($args[$x], $names) ? NULL : $args[$x].$args[1]), $x++);
return trim($m, $args[1]);
}else{
return 'No zip file in descriptor!';
}
}
example:
$zip=zip_open('any_zip_file_zip');
var_dump(zip_entries_nonexists_list($zip, '<br />', 'photo_1.jpg', 'photo_2.jpg'));
it will return if not found files:
photo_1.jpg<br />photo_2.jpg

If you just want to unzip a zip folder an alternative to some of the lengthy functions below is:
<?
function unzip($zip_file, $src_dir, $extract_dir)
{
copy($src_dir . "/" . $zip_file, $extract_dir . "/" . $zip_file);
chdir($extract_dir);
shell_exec("unzip $zip_file");
}
?>
You don't need the ZIP extension for this.

Zip Class from Devin Doucette at phpclasses.org
Allows the creation of tar, gzip, bzip2, and zip archives, and the extraction of tar, gzip, and bzip2.
Supports relative paths/no paths, comments, and recursing through subdirectories.
Can write file to disk, allow user to download directly, or return file contents in a string or an array.
Does not require any external programs to run.
Here is a link: http://www.phpclasses.org/browse/package/945.html

If (as me) all you wanted to do is store a big string (for example, a serialized array or the like) in a mysql BLOB field, remember that mysql has a COMPRESS() and UNCOMPRESS() pair of functions that do exactly that. Compression/decompression is therefore available also when accessing the DB from other languages like java, etc.

I slightly changed the extension of Schore that makes function operate more effiecently - less number of itterations. This is most important in dealing with HUGE archives. I also add comment to brief the code. Fits for WIN users.
function unzip($dir,$file) {
$zip = zip_open($dir.$file.".zip"))

I have had problems with the function of kristiankjaer to unpack zipfiles within any directories.
So I wrote a little extension.
<?php
function unpackZip($dir,$file) {
if ($zip = zip_open($dir.$file.".zip")) {
if ($zip) {
mkdir($dir.$file);
while ($zip_entry = zip_read($zip)) {
if (zip_entry_open($zip,$zip_entry,"r")) {
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
$dir_name = dirname(zip_entry_name($zip_entry));
if ($dir_name != ".") {
$dir_op = $dir.$file."/";
foreach ( explode("/",$dir_name) as $k) {
$dir_op = $dir_op . $k;
if (is_file($dir_op)) unlink($dir_op);
if (!is_dir($dir_op)) mkdir($dir_op);
$dir_op = $dir_op . "/" ;
}
}
$fp=fopen($dir.$file."/".zip_entry_name($zip_entry),"w");
fwrite($fp,$buf);
zip_entry_close($zip_entry);
} else
return false;
}
zip_close($zip);
}
} else
return false;
return true;
}
?>

Here is a function if all you need is to unpack an archive:
function unpackZip($dir,$file) {
$root=$_SERVER['DOCUMENT_ROOT'];
if ($zip = zip_open($root.$dir.$file.".zip")) {
if ($zip) {
mkdir(".".$dir.$file);
while ($zip_entry = zip_read($zip)) {
if (zip_entry_open($zip,$zip_entry,"r")) {
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
$fp=fopen(".".$dir.$file."/".zip_entry_name($zip_entry),"w");
fwrite($fp,$buf);
zip_entry_close($zip_entry);
} else
return false;
}
zip_close($zip);
}
} else
return false;
return true;
}

PKZipfiles (or Winzip files) can be easily created by using my Ziplib class, can be found on http://sourceforge.net/projects/phpziplib . All it requires is PHP to be compiled with zlib, and support for classes(don't know when they've been added, but I think with PHP4 you're safe).

If you don't have the --with-zip=DIR compile option and can't change it, but you do have --with-pear, then you can use the pear Archive_Zip class available at http://cvs.php.net/pear/Archive_Zip/
As of 2004-06-23, the class isn't packaged and auto-documented yet, but like all pear classes, the comments are extremely verbose and helpful, and you can download the php file as a standalone. Just include the Zip.php in your project, and you can use the class.

If you want to unzip an password protected file with php..try the following command....it works in Unix/Apache environment...I haven't tested in any other environment...
system("`which unzip` -P Password $zipfile -d $des",$ret_val)
Where $zipfile is the path to the .zip to be unzipped and $des is path to the destination directory.....here both absolute and relative path to the script (which contains this system command) will work...
if everything runs well...file should be unzipped at the $des directory..and you will get 0 value for $ret_val , which means success(info-zip.org)

I have written an OpenSource ZIP2FTP interface, which actually takes a given ZIP file and decompresses it in the folder on an FTP server you specify...
Therefore it may be quite interesting for you people interested in ZIP, its adress is http://zip2ftp.alishomepage.com ; those who directly want the source may visit http://zip2ftp.alishomepage.com/?do=getSource

As of lately this extension has moved to PECL. You find it at it's new home at http://pecl.php.net/package/zip.
`pear install http://pecl.php.net/get/zip-1.0.tgz ` installs it, use dl('zip.so'); to load it after successful installation.

"If you just want to unzip everything of a zip file in a directory"
Watch out with that function, your fopen function uses 'r' instead of 'rb' and the fwrite does not include a filesize. So if you have binary files into that zip file (what you probably do), it will go wrong...

Sometimes you may not be able to install the necessary resources to run the ZIP lib. Maybe because you have no control of the server, or maybe because you cannot find the correct libraries for your php...
Anyway do not despair, there is another solution!
I was in this situation (my client could not install it on the server) so I developed a small libraryin pure PHP that is compatible with PHP's own lib but uses the commandline 'unzip' command directly form PHP. You can configure it to use any commandline unzipping tool (so it should work even with other compressed files, as long as there is a commandline tool). It should work on most platforms with an unzip command (Win32 included) although I have tested only under unix.
What it does exactly, is replacing all the functions of the Zip library with equivalent ones. So the example in this page will work (just rename every zip_... function m_zip_...):
<?php
$zip =m_zip_open("/tmp/test2.zip");
if ($zip) {
while ($zip_entry = m_zip_read($zip)) {
echo "Name: " . m_zip_entry_name($zip_entry) . "\n";
echo "Actual Filesize: " . m_zip_entry_filesize($zip_entry) . "\n";
echo "Compressed Size: " . m_zip_entry_compressedsize($zip_entry) . "\n";
echo "Compression Method: " . m_zip_entry_compressionmethod($zip_entry) . "\n";
if (m_zip_entry_open($zip, $zip_entry, "r")) {
echo "File Contents:\n";
$buf = m_zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
echo "$buf\n";
m_zip_entry_close($zip_entry);
}
echo "\n";
}
m_zip_close($zip);
}
?>
The library will create a new folder and call unzip on the file when you call m_zip_open().
It will get rid of all the unzipped things when you call m_zip_close().
It will walk the directory structure of the ZIP file as you call m_zip_read($zip) getting into directories and then out again.
Then you will be able to read chunks of (or th whole) files with m_zip_entry_read()
: : : INCOMPATIBILITIES : : :
Once the zipfile is unzipped, I will have no way to know the size of the entries or the compression methods, so the functions m_zip_entry_compressedsize() and m_zip_entry_compressionmethod() just return a '?'.
Of course what zipfiles will be compatible and what not will dependo on the command line tool you choose to use.
: : : CONFIGURATION : : :
There are two things to setup:
A path to a directory where we can create subfolders and unzip things:
define('UNZIP_DIR','/data/fandango/html/update/unzipped/');
The command to invoke to unzip the files:
define('UNZIP_CMD','unzip -o @_SRC_@ -x -d @_DST_@');
DO NOT REMOVE THE @_SRC_@ and @ _DST_@ markers. This is where the library will put the source file name you pass and the destination subfolder (it will create a subfolder of UNZIP_DIR and pass that)
: : : DOWNLOAD : : :
You will find the library and a demo file (with the example on this page) at http://esurfers.com/m-zip/

just a not of caution--using the dynamic zip class mentioned earlier seems to cause issues with high ascii characters (their values are not preserved correctly, and the file will not unzip)

If you just want to unzip everything of a zip file in a directory (and create unexisting directories), let's try this:
function unzip($file, $path) {
$zip = zip_open($file);
if ($zip) {
while ($zip_entry = zip_read($zip)) {
if (zip_entry_filesize($zip_entry) > 0) {
// str_replace must be used under windows to convert "/" into "\"
$complete_path = $path.str_replace('/','\\',dirname(zip_entry_name($zip_entry)));
$complete_name = $path.str_replace ('/','\\',zip_entry_name($zip_entry));
if(!file_exists($complete_path)) {
$tmp = '';
foreach(explode('\\',$complete_path) AS $k) {
$tmp .= $k.'\\';
if(!file_exists($tmp)) {
mkdir($tmp, 0777);
}
}
}
if (zip_entry_open($zip, $zip_entry, "r")) {
$fd = fopen($complete_name, 'w');
fwrite($fd, zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)));
fclose($fd);
zip_entry_close($zip_entry);
}
}
}
zip_close($zip);
}
}
To use this function:
unzip('c:\\file.zip','c:\\temp\\'); // BE CAREFULL: second argument *MUST* finish by a "\" ! ("/" under *nix)

Watch out with archives that contain subfolders if you're using the zip functions to extract archives to actual files. Let's say you're trying to extract foldername/filename.txt from the archive. You can't fopen a directory that doesn't exist, so you'll have to check for the existance of directory foldername and create it if it isn't found, then fopen foldername/filename.txt and begin writing to that.

WOW ... after weeks and weeks of research I thought I'd make somebody elses life a little easier. If you're wondering how to make PHP 4.2.3 read windows zip files (winzip, pkzip, etc) do this:
NOTE: THIS IS FOR WINDOWS SERVERS NOT LINUX OR OTHER. You need zziplib for Linux. http://zziplib.sourceforge.net/
ON PHP WINDOWS SERVER
1) Grab the php_zip.dll from the extensions dir in php-4.3.0pre2-Win32.zip
2) Add a line extension=php_zip.dll to your php.ini
3) Restart your web server
php_zip.dll obviously works on PHP 4.3.0pre2 but you can't run Zend Optimizer on PHP 4.3 (yet). You can run Zend Optimizer on PHP 4.2.3 but it doesn't ship with php_zip.dll. The php_zip.dll that ships with PHP 4.3.0pre2 may even work with older version but I haven't tested that.
For documentation on how to use the zip functions (not the gzip functions that are documented on the php site) go here:

For creating zip files, I highly suggest that you have a look at the class used in phpMyAdmin. It makes it very easy to do and it appears to be opensource.

- look at - http://zipios.sf.net -
it is a C++ class that can also write zip files.
it is modelled after the resp. java interface.
Please also note that I (Guido Draheim) can not
answer questions on compiling zziplib-support
into php, I did not add it, and I do not know
anything about the php module interface. If you
find bugs or have suggestions for more features
then I would be pleased to hear about it. TIA, guido

If you are looking for a way to create ZIP files dynamically in PHP, you should look at the wonderful zipfile class.
It seems there is no official page for this class. You may get it by retrieving the zip.lib.php from the PhpMyAdmin 2.5.2:
