/**
|
|
* Name: Archive File Handler
|
|
* Author: Shish <webmaster@shishnet.org>
|
|
* Description: Allow users to upload archives (zip, etc)
|
|
* Documentation:
|
|
* Note: requires exec() access and an external unzip command
|
|
* <p>Any command line unzipper should work, some examples:
|
|
* <p>unzip: <code>unzip -d "%d" "%f"</code>
|
|
* <br>7-zip: <code>7zr x -o"%d" "%f"</code>
