CVII. Zip File Functions (Read Only Access) This module uses the functions of the ZZIPlib library by Guido Draheim to transparently read ZIP compressed archives and the files inside them. 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. 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. Note: Zip support before PHP 4.1.0 is experimental. This section reflects the Zip extension as it exists in PHP 4.1.0 and later. Example Usage This example opens a ZIP file archive, reads each file in the archive and prints out its contents. The test2.zip 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);}?>

抄来的一些资料: 常用的壓縮程式 -- UNIX 篇(1)
gzip
附屬檔名: gz
特性一: 為網路上最常使用的一種壓縮程式
特性二: 壓縮與解壓用的是同一個程式
例: 壓縮: gzip -9 test.tar
解壓: gzip -d test.gz
特性三: 因只能壓縮檔案, 故如有目錄要壓縮者, 大都先用 tar
來包裝起來, 故常看到的附屬檔名為 *.tar.gz 或者是 tgz 常用的壓縮程式 -- UNIX 篇(2)
compress, uncompress
compress 是壓縮程式, uncompress 是解壓縮程式, 附屬檔名為 *.Z
pack,unpack
pack 是壓縮程式, unpack 是解壓縮程式, 附屬檔名為 *.z 常用的壓縮程式 -- UNIX 篇(3)
zip, unzip
zip 是壓縮, unzip 是解壓縮, 附屬檔名為 *.zip, 但這個
程式不是原來 UNIX 原有的
tar
tar 原來的用途是將資料放入磁帶機中, 但是因為其可以將
多個目錄放在一個檔案的特性, 故常被用來集合包裝整個目
錄及其檔案, 附屬檔名為 *.tar, 完成後再交予其它壓縮程
式壓縮
急急急急！
在windows下，应该有编译好的zlib支持模块，把相应的dll文件拷到目录下，设定php.ini应该就可以了。但.zip格式就有点麻烦了。
如果以上方法不行，还可以通过调用外部程序的方法来解决。
