    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

    very short version of function for unzipping files with folders structure:
    <?php

    function unzip($file){

            $zip=zip_open(realpath(".")."/".$file);
        if(!    $zip) {return("Unable to proccess file '{$file}'");}

            $e='';

        while(    $zip_entry=zip_read($zip)) {
               $zdir=dirname(zip_entry_name($zip_entry));
               $zname=zip_entry_name($zip_entry);

           if(!    zip_entry_open($zip,$zip_entry,"r")) {$e.="Unable to proccess file '{$zname}'";continue;}
           if(!    is_dir($zdir)) mkdirr($zdir,0777);

               #print "{$zdir} | {$zname} \n";

               $zip_fs=zip_entry_filesize($zip_entry);
           if(empty(    $zip_fs)) continue;

               $zz=zip_entry_read($zip_entry,$zip_fs);

               $z=fopen($zname,"w");
               fwrite($z,$zz);
               fclose($z);
               zip_entry_close($zip_entry);

        }
            zip_close($zip);

        return(    $e);

    With this extension you can Add dirs with files with the ZipArchive Object

    <?php
    /**
    * FlxZipArchive, Extends ZipArchiv.
    * Add Dirs with Files and Subdirs.

    * <code>
    *  $archive = new FlxZipArchive;
    *  // .....
    *  $archive->addDir( 'test/blub', 'blub' );
    * </code>
    */
    class FlxZipArchive extends ZipArchive {
            /**

    this function extract all files and subdirectories, you can choose verbose mode for get paths of files extracted. the function return a msg what indicate the error, if msg is OK, all is done.

    ---

    code:

    <?php
    function unzip($dir, $file, $verbose = 0) {

           $dir_path = "$dir$file";
           $zip_path = "$dir$file.zip";
      
           $ERROR_MSGS[0] = "OK";
           $ERROR_MSGS[1] = "Zip path $zip_path doesn't exists.";
           $ERROR_MSGS[2] = "Directory $dir_path for unzip the pack already exists, impossible continue.";
           $ERROR_MSGS[3] = "Error while opening the $zip_path file.";
      
           $ERROR = 0;
      
       if (    file_exists($zip_path)) {
      
             if (!    file_exists($dir_path)) {
                
                    mkdir($dir_path);

                   else
                          $ERROR = 4;

       return     $ERROR_MSGS[$ERROR];       
       
    }   
    ?>

    example:

    <?php
    $error     = unzip("d:/www/dir/", "zipname", 1);

    echo     $error;
    ?>

    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'];

                $this->entry = zip_read($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

          //Reads the next $count bytes or until the end of the zip entry. Returns the data or false if no data was read.

    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($zip_entry);
           } else
               return     false;
           }
               zip_close($zip);
         }
      } else
         return     false;

      return     true;
    }

    $dir = $_SERVER['DOCUMENT_ROOT']."/"."destdirectory/";
    $file = 'zipfilename_without_extension';
    unpackZip($dir,$file);
    $print = $_SERVER['DOCUMENT_ROOT'];

    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
    function unzip($zipfile)
    {
            $zip = zip_open($zipfile);
        while (    $zip_entry = zip_read($zip))    {
                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);

    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");
    }

    ?>

    You don't need the ZIP extension for this.
