PHP, compress and extract files using PclZip library
PclZip library offers PHP compression and extraction functions for Zip formatted archives. PclZip library can be downloaded from:
http://old.phpconcept.net/pclzip/index.en.php
The user menu can be found HERE.
To include pclzip library:
include_once('pclzip.lib.php');
To add or extract very large file, "memory_limit" value in php.ini needs to be increased. "memory_limit" can also set in the PHP code:
ini_set('memory_limit', '180M');
To initialize a zip instance:
$myzipfile = new PclZip('myzfile.zip');
To create a zip file from image1.jpg and image2.jpg:
$mylist = $archive->create('mydata/image1.jpg,mydata/image2.jpg',
PCLZIP_OPT_REMOVE_PATH, 'data',
PCLZIP_OPT_ADD_TEMP_FILE_ON);
