yp_order
I wrote a simple function to export a zip file to an array. I tested it and works great to up to 1MB archives. (Didn't need it for larger files.)
I use it to upload files to my server in a zip and have it directly extracted along with directory structure.
This function will attempt to use unzip functions in php otherwise will use PCLzip. Instructions and the functions are explained on http://www.tellinya.com/art2/20/unzip-in-php . The code is quite short but effective. Test it as advised on site to unserstand the format it extracts.
And any bug please mention in the comment form as I rely on this code and I'll address them ASAP. This will satisfy the needs of 95% of those that do unzips on the site and will help those with unzip functions not enabled as PCPLzip will handle it as well.
Cheers and n-joy.
CLXXXIII. Zip File Functions
Введение
This module enables you to transparently read or write ZIP compressed archives and the files inside them.
Требования
PHP 4 Bundled
The initial version is bundled in PHP 4 and is available in PECL as version 1.0, see http://pecl.php.net/package/zip. It can only read Zip Archives.
This version uses the functions of the ZZIPlib library by Guido Draheim. You need ZZIPlib version >= 0.10.6.
PECL and PHP 5.2 or later
The newest version is bundled in PHP 5.2.0 or later and available in PECL, as version 1.1.0 or later. It does not require any external library. It can read and write Zip archives when used with PHP 5.1 or later and can only read them when used with PHP4.
Установка
Это расширение PECL не поставляется вместе с PHP. Дополнительная информация, такая как новый версии, скачивание, исходные файлы, информация о разработчике и CHANGELOG, могут быть найдены здесь: http://pecl.php.net/package/zip.
Installation on Linux
Installation when bundled with PHP4
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.
Installation with PECL or bundled with PHP 5.2 or later
In order to use these functions you must compile PHP with zip support
by using the --enable-zip
configure option. It does not require any external library.
Замечание: You can use the PECL version with PHP4. In order to do it you have to disable the bundled Zip extension or recompile PHP without it.
Installation on Windows
Installation when bundled with PHP4
Windows users will enable php_zip.dll inside of php.ini in order to use these functions. В PHP 4 этот DLL находится в директории extensions/ внутри директории бинарного дистрибутива PHP для Windows. Вы можете скачать DLL этого расширения PECL со страницы PHP Downloads или http://snaps.php.net/.
Замечание: Zip support before PHP 4.1.0 is experimental. This section reflects the Zip extension as it exists in PHP 4.1.0 and later.
Installation with PECL or bundled with PHP 5.2 or later
Windows users will enable php_zip.dll inside of php.ini in order to use these functions. В PHP 4 этот DLL находится в директории extensions/ внутри директории бинарного дистрибутива PHP для Windows. Вы можете скачать DLL этого расширения PECL со страницы PHP Downloads или http://snaps.php.net/.
Настройка во время выполнения
Данное расширение не определяет никакие директивы конфигурации в php.ini.
Типы ресурсов
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.
Предопределенные константы
Перечисленные ниже константы определены данным расширением и могут быть доступны только в том случае, если PHP был собран с поддержкой этого расширения или же в том случае, если данное расширение подгружается во время выполнения.
ZipArchive uses class constants. There is three types of constants, Flags (FL_) errors (ER_) or mode (no prefix).

Примеры
Пример 2. Dump the archive details and listing
|
Пример 3. Zip stream wrapper, read an OpenOffice meta info
|
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.

I made a zip stream handler in case your distribution does not have the built in one using the new ZipArchive system. This one also features the ability to grab entries by index as well as by name. It is similar in capabilities to the builtin gzip/bzip2 compression stream handlers (http://us2.php.net/manual/en/wrappers.compression.php) except it does not support writing.
To use:
fopen('zip://absolute/path/to/file.zip?entryname', $mode) or
fopen('zip://absolute/path/to/file.zip#entryindex', $mode) or
fopen('zip://absolute/path/to/file.zip', $mode)
$mode can only be 'r' or 'rb'. In the last case the first entry in the zip file is used.
<?php
class ZipStream {
public $zip; //the zip file
public $entry; //the opened zip entry
public $length; //the uncompressed size of the zip entry
public $position; //the current position in the zip entry read
//Opens the zip file then retrieves and opens the entry to stream
public function stream_open($path, $mode, $options, &$opened_path) {
if ($mode != 'r' && $mode != 'rb') //only accept r and rb modes, no writing!
return false;
$path = 'file:///'.substr($path, 6); //switch out file:/// for zip:// so we can use url_parse
$url = parse_url($path);
//open the zip file
$filename = $url['path'];
$this->zip = zip_open($filename);
if (!is_resource($this->zip))
return false;
//if entry name is given, find that entry
if (array_key_exists('query', $url) && $url['query']) {
$path = $url['query'];
do {
$this->entry = zip_read($this->zip);
if (!is_resource($this->entry))
return false;
} while (zip_entry_name($this->entry) != $path);
} else { //otherwise get it by index (default to 0)
$id = 0;
if (array_key_exists('fragment', $url) && is_int($url['fragment']))
$id = $url['fragment']*1;
for ($i = 0; $i <= $id; $i++) {
$this->entry = zip_read($this->zip);
if (!is_resource($this->entry))
return false;
}
}
//setup length and open the entry for reading
$this->length = zip_entry_filesize($this->entry);
$this->position = 0;
zip_entry_open($this->zip, $this->entry, $mode);
return true;
}
//Closes the zip entry and file
public function stream_close() { @zip_entry_close($this->entry); @zip_close($this->zip); }
//Returns how many bytes have been read from the zip entry
public function stream_tell() { return $this->position; }
//Returns true if the end of the zip entry has been reached
public function stream_eof() { return $this->position >= $this->length; }
//Returns the stat array, only 'size' is filled in with the uncompressed zip entry size
public function url_stat() { return array('dev'=>0, 'ino'=>0, 'mode'=>0, 'nlink'=>0, 'uid'=>0, 'gid'=>0, 'rdev'=>0, 'size'=>$this->length, 'atime'=>0, 'mtime'=>0, 'ctime'=>0, 'blksize'=>0, 'blocks'=>0); }
//Reads the next $count bytes or until the end of the zip entry. Returns the data or false if no data was read.
public function stream_read($count) {
$this->position += $count;
if ($this->position > $this->length)
$this->position = $this->length;
return zip_entry_read($this->entry, $count);
}
}
//Register the zip stream handler
stream_wrapper_register('zip', 'ZipStream'); //if this fails there is already a zip stream handler and we will just use that one

Lennart Poot's example of using phpMyAdmin's zip library is missing the echo that will actually output the final zip file.
At the end (but before the exit which isn't needed anyway), add this line:
echo $dump_buffer;

This is the function I use to unzip a file.
It includes the following options:
* Unzip in any directory you like
* Unzip in the directory of the zip file
* Unzip in a directory with the zipfile's name in the directory of the zip file. (i.e.: C:\test.zip will be unzipped in C:\test\)
* Overwrite existing files or not
* It creates non existing directories with the function Create_dirs($path)
You should use absolute paths with slashes (/) instead of backslashes (\).
I tested it with PHP 5.2.0 with php_zip.dll extension loaded
<?php
/**
* Unzip the source_file in the destination dir
*
* @param string The path to the ZIP-file.
* @param string The path where the zipfile should be unpacked, if false the directory of the zip-file is used

Hi, all
There are lot of functions given below which etracts files, but what they lack is setting file permissions. On some servers file permissions are very important and the script cease to work after creating first directory, So I have added chmod to the code. There is only one limitation to the code, files without file extension are neither treated as files or directories so they are not chmoded, anyway this does not affect the code. Hope this helps.
<?php
function unpackZip($dir,$file) {
if ($zip = zip_open($dir.$file.".zip")) {
if ($zip) {
mkdir($dir.$file);
chmod($dir.$file, 0777);
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($dir_op);
chmod($dir_op, 0777);
$dir_op = $dir_op . "/" ;
}

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.

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");
24-Sep-2006 07:46
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.

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 use the function unpackZip from schore at NOSPAM dot hotmail dot com.
it appears that the fclose instruction is missing. Without that instruction, i've got some trouble to unpack zip file with recursive folders.
Here is the new code with the missing instruction
<?php

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.$file.".zip"))
if ($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));
$hostDir = dirname(zip_entry_name($zip_entry));
/* for root "." directory nothing to be done coase root directory was
created before the while-loop statement */
if ($hostDir != ".") {
$absPathToHostDir = $dir.$file."\\";
/* Convrerts path string upon to FMS & OS-WIN configuration */
foreach ( explode("/",$hostDir) as $k)
$absPathToHostDir = $absPathToHostDir . $k . "\\";
$absPathToHostDir = substr($absPathToHostDir,0,-1);

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)

"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/

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:

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

Check out these pages on the Zend Web Site. The author of the zipfile class explains how his class runs!
Have fun ;)

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:
