PHP壓縮與歸檔—Zip

此擴充功能可以讓你透明地讀寫ZIP壓縮文件以及它們裡面的檔案。

在PHP5.2以後，為了使用這些函數，必須在編譯 PHP 時用 --enable-zip 設定選項來提供 zip 支援。

Example #1 建立一個Zip 歸檔

<?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 輸出文檔細節和列表

<?php
    $za = new ZipArchive();
    $za->open(&#39;test_with_comment.zip&#39;);
    print_r($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 流封裝，讀取一個OpenOffice 文件的元資訊

Example #3 Zip 流封裝，讀取一個OpenOffice 文件的元資訊

<?php
    $reader = new XMLReader();
    $reader->open(&#39;zip://&#39; . dirname(__FILE__) . &#39;/test.odt#meta.xml&#39;);
    $odt_meta = array();
    while ($reader->read()) {
        if ($reader->nodeType == XMLREADER::ELEMENT) {
            $elm = $reader->name;
        } else {
            if ($reader->nodeType == XMLREADER::END_ELEMENT && $reader->name == &#39;office:meta&#39;) {
                break;
            }
            if (!trim($reader->value)) {
                continue;
            }
            $odt_meta[$elm] = $reader->value;
        }
    }
    print_r($odt_meta);
?>
