示例

    示例 #1 创建 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();
    ?>

    示例 #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";
    ?>

    示例 #3 Zip 流封装，读取 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 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。

    示例 #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);

    }
    ?>
