PHP generated compressed file Development example

Approximate requirements:

Each order has a number of file attachments, in the download of the time you want to the current order files automatically packaged into a compressed package download

Details Required: Current order number _ Month Day + time. Zip For example:

1. Generate compressed files, compressed file name format:

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

3. Click the download package, the system begins to package the compressed file, and automatically start the download after packaging is finished

4. To prevent exposing the compressed package file path, you need to rename the downloaded archive file name

Please see the following code for the specific operating mode:

File path:

Compressed package file storage path:/upload/zipfile/

Uploaded attachment Storage path:/upload/file/

1. Basic Profile file config.inc.php placed in the 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. Compress package program code files getzip.php

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

This is the PHP extension class, since the php5.2 version has been supported this extension, if you are using the error, check the php.ini inside the EXTENSION=PHP_ Zip.dll in front of the semicolon has not been removed, and then restart Apache to use this class library.
