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);}?>
