You can consider Rar as a powerful and reliable archiver. This extension allows you to read Rar archives but does not support writing because it is not supported by the library UnRar and it prohibits directly by the license. WinRAR is a powerful archive manager. It can backup your data and Reduce the size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format. These functions are available in the standard PHP module, which is always available.

You can use the PECL installation wizard to install the Rar extension, using the following command: pecl-v install rar. You can also download the tar.gz package and install Rar manually. WinRAR can work with SFX archives as with any other archives, so if you do not want to run a received SFX archive. SFX archives usually have .exe extension just like any other executable file. A SFX (SelF-eXtracting) archive is an archive merged with an executable module, which is used to extract files from the archive when executed.

You can use the following steps for Installation of the Rar :

gunzip rar-xxx.tgz
 tar-xvf rar-xxx.tar
 cd rar-xxx
 phpize
 . / configure & & make & & make install

Windows users must enable the library php_rar.dll in php.ini to use these functions.

I think that you should also know about the Resource Types of the Rar Archive. This extension saves 2 inner classes: The representation of the archive, returned by rar_open () and the representation of entries returned by the functions rar_list () and rar_entry_get (). Also the information about the class RarArchive is necessary. This class represents a RAR archive, which can be formed of several volumes (parts) and can contain multiple entries RAR. The objects of this class can be browsed, allowing access to entries in the respective RAR archives. These entries can also be obtained via methods RarArchive:: GetEntry and RarArchive:: list.

I have provided you with an example of RAR extension filesystem. So just have a look at the following example :

<?php

$rar_file = rar_open('demo.rar') or die("Unable to open Rar archive");

$entries = rar_list($rar_file);

foreach ($entries as $entry) {
    echo 'Filename: ' . $entry->getName() . "\n";
    echo 'Packed size: ' . $entry->getPackedSize() . "\n";
    echo 'Unpacked size: ' . $entry->getUnpackedSize() . "\n";

    $entry->extract('/dir/extract/to/');
}

rar_close($rar_file);

?>
