# 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);

    }
    ?>
