范例

Example #1 创建一个 Zip 归档

  <?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 输出文档细节和列表

  <?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 流封装，读取一个 OpenOffice 文件的元信息

  <?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 );
 ?>

此例使用了旧的 API（PHP 4），它打开了一个 ZIP 文件归档，读取归档里的每个文件，并输出文件内容。此例用到的 test2.zip 文档是 ZZIPlib 源分布里测试文档中的一个。

Example #4 Zip 使用范例

  <?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 );

}
 ?>

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);

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!"; ?>
