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
* @param boolean Indicates if the files will be unpacked in a directory with the name of the zip-file (true) or not (false) (only if the destination directory is set to false!)
* @param boolean Overwrite existing files (true) or not (false)
*
* @return boolean Succesful or not

// For every file in the zip-packet
while ($zip_entry = zip_read($zip))

// If the file is not in the root dir

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.

Hi,
if you have the RAW CONTENT OF THE ZIP FILE IN A STRING ONLY and you can't create files on your server (because of the SAFE MODE) to be able to create a file which you can then pass to zip_open(), you'll be having hard times getting the uncompressed content of your ZIP data.
This may help:
I've written simple ZIP decompression function for decompressing the first file from the archive stored in a string (no matter what file it is). It's just about parsing a local file header of the first file, getting raw compressed data of that file and decompression of that data (usually, data in ZIP files are compressed by 'DEFLATE' method, so we'll just decompress it by gzinflate() function then).
<?php
function decompress_first_file_from_zip($ZIPContentStr){
//Input: ZIP archive - content of entire ZIP archive as a string
//Output: decompressed content of the first file packed in the ZIP archive
//let's parse the ZIP archive
//(see 'http://en.wikipedia.org/wiki/ZIP_%28file_format%29' for details)
//parse 'local file header' for the first file entry in the ZIP archive
if(strlen($ZIPContentStr)<102){
//any ZIP file smaller than 102 bytes is invalid
printf("error: input data too short<br />\n");
return '';
}
$CompressedSize=binstrtonum(substr($ZIPContentStr,18,4));
$UncompressedSize=binstrtonum(substr($ZIPContentStr,22,4));
$FileNameLen=binstrtonum(substr($ZIPContentStr,26,2));
$ExtraFieldLen=binstrtonum(substr($ZIPContentStr,28,2));
$Offs=30+$FileNameLen+$ExtraFieldLen;
$ZIPData=substr($ZIPContentStr,$Offs,$CompressedSize);
$Data=gzinflate($ZIPData);
if(strlen($Data)!=$UncompressedSize){
printf("error: uncompressed data have wrong size<br />\n");
return '';
}
else return $Data;
}
function binstrtonum($Str){
//Returns a number represented in a raw binary data passed as string.
//This is useful for example when reading integers from a file,
// when we have the content of the file in a string only.
//Examples:
// chr(0xFF) will result as 255
// chr(0xFF).chr(0xFF).chr(0x00).chr(0x00) will result as 65535
// chr(0xFF).chr(0xFF).chr(0xFF).chr(0x00) will result as 16777215
$Num=0;
for($TC1=strlen($Str)-1;$TC1>=0;$TC1--){ //go from most significant byte
$Num<<=8; //shift to left by one byte (8 bits)
$Num|=ord($Str[$TC1]); //add new byte
}
return $Num;
}
?>
ENJOY!!!

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

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.

Here's a more simple extended class to add a whole directory recursively, keeping the same structure. It uses SPL.
<?php
class MyZipArchive extends ZipArchive
{
/**
*
* Adds a directory recursively.
*
* @param string $filename The path to the file to add.
*
* @param string $localname Local name inside ZIP archive.
*
*/
public function addDir($filename, $localname)
{
$this->addEmptyDir($localname);
$iter = new RecursiveDirectoryIterator($filename, FilesystemIterator::SKIP_DOTS);
foreach ($iter as $fileinfo) {
if (! $fileinfo->isFile() && !$fileinfo->isDir()) {
continue;
}
$method = $fileinfo->isFile() ? 'addFile' : 'addDir';
$this->$method($fileinfo->getPathname(), $localname . '/' .
$fileinfo->getFilename());
}
}
}
?>

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 . "/" ;
}
}
$fp=fopen($dir.$file."/".zip_entry_name($zip_entry),"w+");
chmod($dir.$file."/".zip_entry_name($zip_entry), 0777);
fwrite($fp,$buf);
fclose($fp);
zip_entry_close($zip_entry);

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);
}
}
}

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:
<?php
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:
<?php
$zip=zip_open('any_zip_file_zip');
var_dump(zip_entries_nonexists_list($zip, '<br />', 'photo_1.jpg', 'photo_2.jpg'));
?>
it will return if not found files:
photo_1.jpg<br />photo_2.jpg

If you 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)

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)

You could just use the linux commands
<?php
// Get the date
$date = date("m-d-y");
// Make Zip name
$zipname = "archive/site-script-backup." . $date . ".zip";
// Make a zip file
$cmd = `zip -r $zipname *`;

This is the simplest method to unzip a file. Pass the function your filename and it will unzip it to the current directory of the script with permissions done properly on unix type operating systems. Far simpler to understand and read.
<?php
function unzip($file){
$zip = zip_open($file);
if(is_resource($zip)){
$tree = "";
while(($zip_entry = zip_read($zip)) !== false){
echo "Unpacking ".zip_entry_name($zip_entry)."\n";
if(strpos(zip_entry_name($zip_entry), DIRECTORY_SEPARATOR) !== false){
$last = strrpos(zip_entry_name($zip_entry), DIRECTORY_SEPARATOR);
$dir = substr(zip_entry_name($zip_entry), 0, $last);
$file = substr(zip_entry_name($zip_entry), strrpos(zip_entry_name($zip_entry), DIRECTORY_SEPARATOR)+1);
if(!is_dir($dir)){
@mkdir($dir, 0755, true) or die("Unable to create $dir\n");
}
if(strlen(trim($file)) > 0){
$return = @file_put_contents($dir."/".$file, zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)));
if($return === false){
die("Unable to write file $dir/$file\n");
}
}
}else{
file_put_contents($file, zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)));
}
}
}else{
echo "Unable to open zip file\n";
}
}

Heres a function I wrote that will extract a zip file with the same directory structure...
Enjoy:
<?php

zip_entry_open($zip, $zip_entry);
if (substr(zip_entry_name($zip_entry), -1) == '/') {
$zdir = substr(zip_entry_name($zip_entry), 0, -1);
if (file_exists($zdir)) {
trigger_error('Directory "<b>' . $zdir . '</b>" exists', E_USER_ERROR);
return false;
}
mkdir($zdir);
}
else {
$name = zip_entry_name($zip_entry);
if (file_exists($name)) {
trigger_error('File "<b>' . $name . '</b>" exists', E_USER_ERROR);
return false;
}
$fopen = fopen($name, "w");
fwrite($fopen, zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)), zip_entry_filesize($zip_entry));
}
zip_entry_close($zip_entry);
}
zip_close($zip);

If you just want to unzip a zip folder an alternative to some of the lengthy functions below is:
<?php
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");
