Zip File Functions

简介

This extension enables you to transparently read or write ZIP compressed archives and the files inside them.

需求

PHP 4

The bundled PHP 4 version requires » ZZIPlib, by Guido Draheim, version 0.10.6 or later

PHP 5.2.0 or later

This extension uses the functions of » zlib by Jean-loup Gailly and Mark Adler.

安装

PHP 4

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.

Linux systems

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.

Windows

Windows users need to enable php_zip.dll inside of php.ini in order to use these functions.

PHP 5.2.0 and later

Linux systems

In order to use these functions you must compile PHP with zip support by using the --enable-zip configure option.

Windows

Windows users need to enable php_zip.dll inside of php.ini in order to use these functions.

Installation via PECL

安装此 PECL 扩展库的信息可在手册中标题为 PECL 扩展库安装的一章中找到。更多信息如新版本，下载，源文件，维护者信息以及更新日志等可以在这里找到： » http://pecl.php.net/package/zip.

可以从 » PHP 下载页面或者 » http://snaps.php.net/ 下载此 PECL 扩展的 DLL 文件。

在 PHP 4 中本 DLL 位于 PHP Windows 执行包中的 extensions/ 目录下。

运行时配置

本扩展模块在 php.ini 中未定义任何配置选项。

资源类型

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.

预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

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.
ZIPARCHIVE::EXCL (integer): Error if archive already exists.
ZIPARCHIVE::CHECKCONS (integer): Perform additional consistency checks on the archive, and error if they fail.
ZIPARCHIVE::FL_NOCASE (integer): Ignore case on name lookup
ZIPARCHIVE::FL_NODIR (integer): Ignore directory component
ZIPARCHIVE::FL_COMPRESSED (integer): Read compressed data
ZIPARCHIVE::FL_UNCHANGED (integer): Use original data, ignoring changes.
ZIPARCHIVE::CM_DEFAULT (integer): better of deflate or store.
ZIPARCHIVE::CM_STORE (integer): stored (uncompressed).
ZIPARCHIVE::CM_SHRINK (integer): shrunk
ZIPARCHIVE::CM_REDUCE_1 (integer): reduced with factor 1
ZIPARCHIVE::CM_REDUCE_2 (integer): reduced with factor 2
ZIPARCHIVE::CM_REDUCE_3 (integer): reduced with factor 3
ZIPARCHIVE::CM_REDUCE_4 (integer): reduced with factor 4
ZIPARCHIVE::CM_IMPLODE (integer): imploded
ZIPARCHIVE::CM_DEFLATE (integer): deflated
ZIPARCHIVE::CM_DEFLATE64 (integer): deflate64
ZIPARCHIVE::CM_PKWARE_IMPLODE (integer): PKWARE imploding
ZIPARCHIVE::CM_BZIP2 (integer): BZIP2 algorithm
ZIPARCHIVE::ER_OK (integer): No error.
ZIPARCHIVE::ER_MULTIDISK (integer): Multi-disk zip archives not supported.
ZIPARCHIVE::ER_RENAME (integer): Renaming temporary file failed.
ZIPARCHIVE::ER_CLOSE (integer): Closing zip archive failed
ZIPARCHIVE::ER_SEEK (integer): Seek error
ZIPARCHIVE::ER_READ (integer): Read error
ZIPARCHIVE::ER_WRITE (integer): Write error
ZIPARCHIVE::ER_CRC (integer): CRC error
ZIPARCHIVE::ER_ZIPCLOSED (integer): Containing zip archive was closed
ZIPARCHIVE::ER_NOENT (integer): No such file.
ZIPARCHIVE::ER_EXISTS (integer): File already exists
ZIPARCHIVE::ER_OPEN (integer): Can't open file
ZIPARCHIVE::ER_TMPOPEN (integer): Failure to create temporary file.
ZIPARCHIVE::ER_ZLIB (integer): Zlib error
ZIPARCHIVE::ER_MEMORY (integer): Memory allocation failure
ZIPARCHIVE::ER_CHANGED (string): Entry has been changed
ZIPARCHIVE::ER_COMPNOTSUPP (integer): Compression method not supported.

范例

Example#1 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#2 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#3 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#4 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);

}
?>

in regards to the extracting via unzip.lib.php:


Don't forget to also put in the file path.


Otherwise you end up with a lot of files in the wrong folder...





<?php


require_once("zip.lib.php");


require_once("unzip.lib.php");





$zip = new SimpleUnzip();


$filename = "myzippedfile.zip";


$entries = $zip->ReadFile($filename);





foreach ($entries as $entry){


     $fh = fopen($entry->Path .'/'.$entry->Name, 'w', false);


    fwrite($fh,$entry->Data);


    fclose($fh);


}


?>

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 *`;

Using the same scripts as the last message:



\libraries\zip.lib.php

\libraries\unzip.lib.php



you can also extract all the files included in a zip file. This is my own example:



require_once("zip.lib.php");

require_once("unzip.lib.php");



$zip = new SimpleUnzip();

$filename = "myzippedfile.zip";

$entries = $zip->ReadFile($filename);



foreach ($entries as $entry){

     $fh = fopen($entry->Name, 'w', false);

    fwrite($fh,$entry->Data);

    fclose($fh);

}

Just to second the comments above and say that the zipfile class in phpMyAdmin is excellent. 



There are 2 files when you download phpMyAdmin:



\libraries\zip.lib.php

\libraries\unzip.lib.php



Here is a small example:



$zip = new zipfile();

$filename = "1.jpg";

$fsize = @filesize($filename);

$fh = fopen($filename, 'rb', false);

$data = fread($fh, $fsize);              

$zip->addFile($data,$filename);



$zipcontents = $zip->file();



header("Content-type: application/octet-stream");

header("Content-Disposition: attachment; filename=\"TheZip.zip\"");

header("Content-length: " . strlen($zipcontents) . "\n\n");



// output data

echo $zipcontents;

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);



        foreach ($iter as $fileinfo) {

            if (! $fileinfo->isFile() && !$fileinfo->isDir()) {

                continue;

            }



            $method = $fileinfo->isFile() ? 'addFile' : 'addDir';

            $this->$method($fileinfo->getPathname(), $localname . '/' .

                $fileinfo->getFilename());

        }

    }

}

?>

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);

    }

    zip_close($zip);

    return true;

}

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



/**

     **/



    public function addDir($location, $name) {

        $this->addEmptyDir($name);



        $this->addDirDo($location, $name);

//     } // EO addDir;

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;

Hi,

i modified the function from nielsvandenberge, now you

can also use relative path's, i added also error messages

and another small highlights, have fun.

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

 * @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)

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'];

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);

            }

        }

    }

?>
