Example #1 Create a Zip archive

$zip

Example #2 Dump the archive details and listing

$za = new ZipArchive();$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";

Example #3 Zip stream wrapper, read an OpenOffice meta info

$reader = new XMLReader();$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

$zip

All these examples will not work if the php script has no write access within the folder.

Although you may say this is obvious, I found that in this case, $zip->open("name", ZIPARCHIVE::CREATE) doesn't return an error as it might not try to access the file system but rather allocates memory.

It is only $zip->close() that returns the error. This might cause you seeking at the wrong end.

you can use this code for reading JAR files (java archives)

JAR files use the same ZIP format, so can be easily read

$zf = zip_open(realpath('D:/lucene/allinone/lucene-core.jar')); $i=1;
while($zf && $ze = zip_read($zf)) {
    $zi[$i]['zip entry name']= zip_entry_name($ze);
    $zi[$i]['zip entry filesize']= zip_entry_filesize($ze);
    $zi[$i]['zip entry compressed size']= zip_entry_compressedsize($ze);
    $zi[$i]['zip entry compression method']= zip_entry_compressionmethod($ze);
    $zi[$i]['zip entry open status'] = zip_entry_open($zf,$ze);
    //$zi[$i]['zip entry file contents'] = zip_entry_read($ze,100);
    $i++;
}
print_r($zi);
zip_close($zf);

        $zip = new ZipArchive;
    $zip->open('teste.zip');
    $zip->extractTo('./');
    $zip->close();
        echo "Ok!";
?>

1) If you want to add files to a ZIP archive but you don't know if the ZiP file exists or not, you MUST check: this changes the way you open it !.
2) you can not append multiple flags, can use only one (or none).

If the zip does not exists, open it with:
$ziph->open($archiveFile, ZIPARCHIVE::CM_PKWARE_IMPLODE)
(or a different compression method)

If the zip already exists, open it with:
$ziph->open($archiveFile)
or
$ziph->open($archiveFile, ZIPARCHIVE::CHECKCONS)

Example: make backup files every hour and ZIP them all in a daily ZIP archive, so you want to get only one ZIP per day, each ZIP containing 24 files:
  function archivebackup($archiveFile, $file, &$errMsg)
  {
    $ziph = new ZipArchive();
    if(file_exists($archiveFile))
    {
      if($ziph->open($archiveFile, ZIPARCHIVE::CHECKCONS) !== TRUE)
      {
        $errMsg = "Unable to Open $archiveFile";
        return 1;
      }
    }
    else
    {
      if($ziph->open($archiveFile, ZIPARCHIVE::CM_PKWARE_IMPLODE) !== TRUE)
      {
        $errMsg = "Could not Create $archiveFile";
        return 1;
      }
    }
    if(!$ziph->addFile($file))
    {
      $errMsg = "error archiving $file in $archiveFile";
      return 2;
    }
    $ziph->close();

        return

If you find your zip file not being created make sure every file you are adding to the zip is valid.  If even one file is not available when zip->close is called then the archive will fail and your zip file won't be created.
