此擴(kuò)展可以讓你透明地讀寫(xiě)ZIP壓縮文檔以及它們里面的文件。

在PHP5.2以后，為了使用這些函數(shù)，必須在編譯 PHP 時(shí)用?--enable-zip?配置選項(xiàng)來(lái)提供 zip 支持。

Example #1 創(chuàng)建一個(gè) 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(xì)節(jié)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: $in';print_r($za->statIndex($i)); } echo 'numFile:' . $za->numFiles . 'n';?>

Example #3 Zip 流封裝，讀取一個(gè) 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);?>

此例使用了舊的 API（PHP 4），它打開(kāi)了一個(gè) ZIP 文件歸檔，讀取歸檔里的每個(gè)文件，并輸出文件內(nèi)容。此例用到的?test2.zip?文檔是 ZZIPlib 源分布里測(cè)試文檔中的一個(gè)。

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($zip_entry)); echo '$bufn'; zip_entry_close($zip_entry); } echo 'n';}zip_close($zip); }?>
