Hướng dẫn download file unzipper php

Script này thực tế ít sử dụng hiện nay do các server đều hỗ trợ và cung cấp công cụ controler cho các bạn quản lý (Cpanel11, Directadmin, Vesta, Koloxo…) tuy nhiên nếu bạn nào sử dụng Froxlor hay các hosting miễn phí như Hostinger thì mình thấy nó không hỗ trợ tính năng này.

Hôm nay Tú cần cài đặt 1 Website trên Hostinger thì thấy rằng Hosting không hỗ trợ như trước, nó đẩy phần quản lý file sang net2ftp.com . Mình cũng dùng nó nhưng bị lỗi gì đó, không hiểu họ làm gì mà không thể chọn được file và unzip.

Thực tế cũng chẳng dám dùng Web FTP nhiều vì sợ vớ vẩn bị lưu user và pass hosting thì đen. Tú có check các dịch vụ Web FTP khác thì giờ không còn site nào hỗ trợ nữa, vì thế giải pháp cuối cùng là sử dụng Php Script để unzip code.

Unzipper – nzip/Ziper file, folder nếu Hosting không hỗ trợ.

Đúng như tên gọi của nó, đoạn mã Php này sẽ giúp bạn có thể unzip thư mực, zip thư mục để tải về một cách đơn giản. Để chạy được script này thì phiên bản php của server yêu cầu từ 5.3 đến < 5.6. Một số server giờ bọn mình còn dùng tới 5.7 rồi :D.

Giao diện của Unziper

Script này được tác giả Ndeet đưa lên trên github và bạn có thể tải về nó tại đây

Cách sử dụng Unziper

Bước 1: Bạn sử dụng FTP Upload (như Filezilla hay CuteFtp, LeapFtp…) để tải file ZIP của các bạn lên hosting vào cùng thư mục chứa file unzipper.php

Bước 2: Bạn truy cập file unzipper.php trên hosting.

Bước 3: Script này sẽ tự động lấy danh sách các file .zip nằm cùng cấp với nó.

Bước 4: Bạn điền path (tên thư mục mà bạn muốn nội dung file zip được nén ra đó)

Bước 5: Nhấn Unzip Archive

Khi cần Ziper file và folder để tải về thì làm tương tự.

Chúc các bạn thành công!

Web designers and developers know how it’s necessary to compress files into one zip archive when it comes to uploading a huge number of files to the server. This also means that you need to unzip the file after downloading it.
As for web developers, they attempt to access all the kinds of PHP libraries. The sizes of some are comparable to the size of the zip archive itself.
So, from this tutorial, you’ll learn how to unzip files on your server using unzipper.php script. Still, before we start, let’s mention basic facts about PHP Unzipper:
• It’s really an indispensable tool at every time you need to upload a lot of files and folders to the site.
• In order to save your time and traffic, it’s enough to upload only one zip archive to the server, and quickly unzip it using unzipper.php script.
• In addition to the unpacking function, it’s possible to view the directory structure on the site. As well, there’s also the option to view the contents of zip archives on the server without unpacking it.
• The script goes with administrator authorization by login and password. It’s fully easy to install.

Unzipping Files on Server with Unzipper.php

1. First, you need to download unzipper.php script to your hard drive.
   Open your hosting server cPanel and navigate to the File Manager tool. Select Upload option in the top panel.
2. You can also upload it using FTP client (e.g., FileZilla, Total Commander).
3. Browse unzipper.php file and upload it to your server. You need to place it in the same directory where you have a ZIP archive.
4. Open your browser window and access your website. Add unzipper.php at the end of the link (e.g., http://your-site.com/unzipper.php).
5. Select the file to unzip in your browser window and use additional options to define, whether you want to delete the ZIP archive after extraction, or you want to keep it.
6. Click Unzip button in order to extract the archived file.

Wrapping It Up

If you have to copy scripts containing a large number of files (for example, content management systems, blogs) to the FTP server quite often, then you can use a more convenient way to upload them. First of all, pack them in a ZIP archive and later unpack them directly on the server. Today, we’ve shown how to do this using unzipper.php script.
What do you think of this option to unzip files on the server? Agree that the download process is really faster if you upload only one file than all the files individually. When a cloud of files is downloaded, the FTP client accesses the server multiple times after each file, which takes a certain amount of time. Wait for more useful tips!

The Unzipper is a PHP script that extracts .zip, .rar or .gz archives on webservers.
It detects .zip/.rar/.gz archives and let you choose which one to extract (if there are multiple archives available). It also supports creating Zip archives.
- It is useful if you not have access to a File-Manager, and you want to upload a lot of files (php framework or image collection) as archive.

• To download the script, click on this link: Download PHP Unzipper (79 KB).

Requirements

- PHP 5.3 and newer.
- PHP Rar extension (needed only if you want to extract Rar archive).

Usage

1. Copy the script code from this page, or Download it from the link above, and save it into a .php file on your server (unzipper.php).
2. Access the "unzipper.php" in your browser.
- To extract a Zip/Rar archive, it must be in the same folder where you have the "unzipper.php" file.
3. Choose .zip, .rar archive or .gz file you want to extract, and click on the "Unzip Archive" button.
