// 22/03/2013 (v2.67)
|
||
// - New method: ->each(function($fileName, $fileInfo) use ($zip)), works as jQuery.
|
||
// Example: $z->each(function($filename) use ($z){ $z->unzip($filename, "unc/".basename($filename)); });
|
||
// 25/07/2012 (v2.664)
|
||
// - unzip was NOT respecting chmod parameters, and always setting to 0777. (thanks to Stef Dawson, http://stefdawson.com)
|
||
// 19/08/2011 (v2.663)
|
||
// - unzipAll was using double slashes (path//filename) to save files. (thanks to Karen Peyton).
|
||
// 09/08/2010 (v2.662)
|
||
// - unzipAll parameters fully reviewed and fixed. Thanks Ronny Dreschler and Conor Mac Aoidh.
|
||
// 12/05/2010 (v2.661)
|
||
// - Fixed E_STRICT notice: "Only variables should be passed by reference". Thanks Erik W.
|
||
// 24/03/2010 (v2.66)
|
||
// - Fixed bug inside unzipAll when dirname is "." (thanks to Thorsten Groth)
|
||
// - Added character "´" to the string conversion table (ex: caixa d´água)
|
||
// 27/02/2010
|
||
// - Removed PHP4 support (file_put_contents redeclaration).
|
||
// 04/12/2009 (v2.65)
|
||
// * Added character translation to decode accents and/or special characters.
|
||
// 10/11/2009
|
||
// * Some security added to avoid malicious ZIP files (relative dirs)
|
||
// * unzipAll() will output by default to same folder of the caller script
|
||
// 25/09/2009
|
||
// - Code optimization to reduce memory usage (uncompress(&$contents))
|
||
// 12/07/2009 (2.62)
|
||
// - Debug messages are shown only when explicit.
|
||
// - New method: getLastError()

# Class dUnzip2 v2.67
|
||
#
|
||
# Author: Alexandre Tedeschi (d)
|
||
# E-Mail: alexandrebr at gmail dot com
|
||
# Londrina - PR / Brazil
|
||
#
|
||
# Objective:
|
||
# This class allows programmer to easily unzip files on the fly.
|
||
#
|
||
# Requirements:
|
||
# This class requires extension ZLib Enabled. It is default
|
||
# for most site hosts around the world, and for the PHP Win32 dist.
|
||
#
|
||
# To do:
|
||
# * Error handling
|
||
# * Write a PHP-Side gzinflate, to completely avoid any external extensions
|
||
# * Write other decompress algorithms
|
||
#
|
||
# Methods:
|
||
# * dUnzip2($filename) - Constructor - Opens $filename
|
||
# * each($cbEach) - Calls $cbEach($filename, $fileinfo) on each compressed file
|
||
# * getList([$stopOnFile]) - Retrieve the file list
|
||
# * getExtraInfo($zipfilename) - Retrieve more information about compressed file
|
||
# * getZipInfo([$entry]) - Retrieve ZIP file details.
|
||
# * unzip($zipfilename, [$outfilename, [$applyChmod]]) - Unzip file
|
||
# * unzipAll([$outDir, [$zipDir, [$maintainStructure, [$applyChmod]]]])
|
||
# * close() - Close file handler, but keep the list
|
||
# * __destroy() - Close file handler and release memory
|
||
#
|
||
# If you modify this class, or have any ideas to improve it, please contact me!
|
||
# You are allowed to redistribute this class, if you keep my name and contact e-mail on it.
|
||
#
|
||
# PLEASE! IF YOU USE THIS CLASS IN ANY OF YOUR PROJECTS, PLEASE LET ME KNOW!
|
||
# If you have problems using it, don't think twice before contacting me!
