PHP generates a compressed file instance _php instance

Approximate requirements:

Each order has multiple file attachments, and when downloading, you want to automatically package the files of the current order into a compressed package download

Detail requirements: Current order number _ month/year date + time. zip For example:

1. Generate compressed file, compressed file name format:

2. Compressed file stored in the root directory/upload/zipfile//Custom compressed file name. zip

3. Click to download the package, the system began packaging compressed files, packaging completed automatically start downloading

4. In order to prevent the exposure of compressed package file path, you need to rename the downloaded compressed package file name

For specific operating modes, see the following code:

File path:

Compressed package File Store Path:/upload/zipfile/

Uploaded attachment store path:/upload/file/

1. Basic Profile file config.inc.php placed in system root directory

Define (' Sys_root ', str_replace ("\", '/', dirname (__file__)));
Define (' Sys_upload ', sys_root. /upload/file ');
Define (' Sys_download ', sys_root. /upload/zipfile ');
Define (' Sys_win ', Strpos (Strtoupper (php_os), ' WIN ')!== false? true:false);
Define (' Sys_chmod ', (' 0777 ') &&! Sys_win)? ' 0777 ': 0);

2. Compression package program code file getzip.php

3.PHP program to generate compressed files need to use the compression class: Ziparchive

This is the extension of PHP, since the php5.2 version has supported this extension, if you are in use when there are errors, look at the php.ini inside the EXTENSION=PHP_ Zip.dll before the semicolon is removed, and then restart Apache so you can use this class library.
