This module uses the functions of the ZZIPlib library by Guido Draheim to transparently read ZIP compressed archives and the files inside them.
這個模塊使用 ZZIPlib 庫(Guido Draheim)來讀取 ZIP 壓縮文檔和里面的文件

Please note that ZZIPlib only provides a subset of functions provided in a full implementation of the ZIP compression algorithm and can only read ZIP file archives. A normal ZIP utility is needed to create the ZIP file archives read by this library.
請注意：這個庫只是ZIP所有擴展功能的一個子集，只能讀取 ZIP 文檔里面的內(nèi)容。一個普通的 ZIP 環(huán)境需要能創(chuàng)建 ZIP 文檔

Zip support in PHP is not enabled by default. You will need to use the --with-zip configuration option when compiling PHP to enable zip support. This module requires ZZIPlib version >= 0.10.6.
PHP 沒有默認(rèn)支持 ZIP,你需要使用 --with-zip 配置編譯你的 PHP.這個模塊需要 ZZPIlib 版本>=0.10.6

Note: Zip support before PHP 4.0.7 is experimental. This section reflects the Zip extension as it exists in PHP 4.0.7 and later.
注意：zip在 4.0.7之前是測試的。這一章寫的是 php4.0.7 和以后版本的東西

Example Usage
This example opens a ZIP file archive, reads each file in the archive and prints out its contents. The test2.php archive used in this example is one of the test archives in the ZZIPlib source distribution.

Example 1. Zip Usage Example

<?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);

}

?>
