Hi guys,

Today i will explained how to extract a zip, gz and rar file in custom extractor class through. This example is so easy to use in php. This example to i am create a custom extractor class in php and then create a three function extractZipArchive,extractGzipFile and extractRarArchive.

This tutorial to your folder to extractor your zip file in your folder. I am create a archive_files and paster to the dummy zip file. Then i am create a second folder in extracted_files to extract your zip file under this folder.

So you are follow for my step by step. So let's start to the example.

Index.php


<?php

// Include and initialize Extractor class

require_once 'Extractor.class.php';

$extractor = new Extractor;

// Path of archive file

$archivePath = 'archive_files/archive.zip';

// Destination path

$destPath = 'extracted_files/';

// Extract archive file

$extract = $extractor->extract($archivePath, $destPath);

if($extract){

echo $GLOBALS['status']['success'];

}else{

echo $GLOBALS['status']['error'];

}

?>

Extractor.class.php

<?php

/**

public static function extract($archive, $destination){

$ext = pathinfo($archive, PATHINFO_EXTENSION);

switch ($ext){

case 'zip':

$res = self::extractZipArchive($archive, $destination);

break;

case 'gz':

$res = self::extractGzipFile($archive, $destination);

break;

case 'rar':

$res = self::extractRarArchive($archive, $destination);

break;

}

return $res;

}

/**

*/

public static function extractZipArchive($archive, $destination){

// Check if webserver supports unzipping.

if(!class_exists('ZipArchive')){

$GLOBALS['status'] = array('error' => 'Your PHP version does not support unzip functionality.');

return false;

}

$zip = new ZipArchive;

// Check if archive is readable.

if($zip->open($archive) === TRUE){

// Check if destination is writable

if(is_writeable($destination . '/')){

$zip->extractTo($destination);

$zip->close();

$GLOBALS['status'] = array('success' => 'Files unzipped successfully');

return true;

}else{

$GLOBALS['status'] = array('error' => 'Directory not writeable by webserver.');

return false;

}

}else{

$GLOBALS['status'] = array('error' => 'Cannot read .zip archive.');

return false;

}

}

/**

* Decompress a .gz File.

*

* @param $archive

* @param $destination

*/

public static function extractGzipFile($archive, $destination){

// Check if zlib is enabled

if(!function_exists('gzopen')){

$GLOBALS['status'] = array('error' => 'Error: Your PHP has no zlib support enabled.');

return false;

}

$filename = pathinfo($archive, PATHINFO_FILENAME);

$gzipped = gzopen($archive, "rb");

$file = fopen($filename, "w");

while ($string = gzread($gzipped, 4096)) {

fwrite($file, $string, strlen($string));

}

gzclose($gzipped);

fclose($file);

// Check if file was extracted.

if(file_exists($destination.'/'.$filename)){

$GLOBALS['status'] = array('success' => 'File unzipped successfully.');

return true;

}else{

$GLOBALS['status'] = array('error' => 'Error unzipping file.');

return false;

}

}

/**

* Decompress/extract a Rar archive using RarArchive.

*

* @param $archive

* @param $destination

*/

public static function extractRarArchive($archive, $destination){

// Check if webserver supports unzipping.

if(!class_exists('RarArchive')){

$GLOBALS['status'] = array('error' => 'Your PHP version does not support .rar archive functionality.');

return false;

}

// Check if archive is readable.

if($rar = RarArchive::open($archive)){

// Check if destination is writable

if (is_writeable($destination . '/')) {

$entries = $rar->getEntries();

foreach ($entries as $entry) {

$entry->extract($destination);

}

$rar->close();

$GLOBALS['status'] = array('success' => 'File extracted successfully.');

return true;

}else{
