Beispiele

Beispiel #1 Erstellen eines Zip-Archivs

<?php

$zip 
= new ZipArchive();
$filename "./test112.zip";

if (
$zip->open($filenameZIPARCHIVE::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();
?>

Beispiel #2 Ausgabe eines detailierten Archivlistings

<?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";
?>

Beispiel #3 Zip Stream Wrapper, Auslesen von OpenOffice Metainformationen

<?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);
?>

Das folgende Beispiel benutzt das alte PHP 4 API, es öffnet eine Zip-Datei, liest jede einzelne Datei im Archiv und gibt deren Inhalt aus. Die in diesem Beispiel genutzte test2.zip Datei ist Teil des Testarchivs des ZZIPlib Quellcodes.

Beispiel #4 Zip Beispiel

<?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_entryzip_entry_filesize($zip_entry));
            echo 
"$buf\n";

            
zip_entry_close($zip_entry);
        }
        echo 
"\n";

    }

    
zip_close($zip);

}
?>

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.

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:
<?php
 
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
0;
  }
?>

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.

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