Php zip extension windows

PHP Zip

PHP extension enables you to transparently read or write ZIP compressed archives and the files inside them.

An example to read(archieve) a zip file through php zip

open('test.zip'); if ($res === TRUE) < echo 'ok'; $zip->extractTo('test'); $zip->close(); > else < echo 'failed, code:' . $res; >?>

Output

Requirements

This extension requires » libzip which is bundled with PHP.

Installation

Linux systems

In order to use these functions you must compile PHP with zip support by using the —enable-zip configure option.

As of PHP 5.6.0 a —with-libzip=DIR configure option has been added to use a system libzip installation.

libzip version 0.11 is required, with 0.11.2 or later recommended.

Windows

As of PHP 5.3 this extension is built-in. Before, Windows users need to enable php_zip.dll inside of php.ini in order to use these functions.

Run-time Configuration

This extension has no configuration directives defined in php.ini.

Resource Types

There are two resource types used in the Zip module. The first one is the Zip directory for the Zip archive, the second Zip Entry for the archive entries.

Predefined Constants

PHP zip also provided some predefined constants, In order to use this extension has either been compiled into PHP or dynamically loaded at runtime.

  PHP Zip Extension

  2. Use the ZipArchive() Class to Create a Zip File in PHP
  3. Use the ZipArchive() Class to Create a Zip File in PHP
  4. How to Use PHP Zip Extension to Get Information of All the Member Files of a ZIP

  Zip extension is one of the most important items in file handling. If you want to compress files or move multiple files through one file, ZIP will be required for this.

  We need to install libzip to perform operations involving the ZIP extension for other platforms.

  Install ZIP Extensions in Ubuntu

  ZIP is already included in windows PHP. We will try to install this library for Ubuntu .

  Run the following commands in Ubuntu to install the libzip library.

  $ sudo apt-get update $ sudo apt-get install -y $ sudo apt-get install libzip-dev 

  Setting up libzip-dev:amd64 (1.7.3-1+ubuntu20.04.1+deb.sury.org+2) . Processing triggers for man-db (2.9.1-1) . Processing triggers for libc-bin (2.31-0ubuntu9.2) . 

  The next step is to install a PHP extension for ZIP .

  $ sudo apt install php7.4-zip 

  Once it is successfully installed, you can use it in PHP.

  Use the ZipArchive() Class to Create a Zip File in PHP

  ZipArchive() is the class used to perform ZIP operations in PHP. Using the ZipArchive() class, create a Zip file.

  php $create_zip = new ZipArchive(); $file_name = "./New.zip";  if ($create_zip->open($file_name, ZipArchive::CREATE)!==TRUE)   exit("cannot open the zip file $file_name>\n"); > $current_dir=getcwd(); //Create files to add to the zip  $create_zip->addFromString("file1 ". time().".txt" , "#1 This is This is the test file number one.\n"); $create_zip->addFromString("file2 ". time().".txt", "#2 This is This is the test file number one.\n"); //add files to the zip  $create_zip->addFile($current_dir . "/too.php","/testfromfile.php"); echo "Number of files added: " . $create_zip->numFiles; echo "
  "; echo "Failed to add:" . $create_zip->status ; $create_zip->close(); ?> 

  The code above creates two text files with some content and adds them into a zip file.

  Use the ZipArchive() Class to Create a Zip File in PHP

  Let’s extract the zip file created in the first code using the ZipArchive() class of PHP.

  php $extract_zip = new ZipArchive; $open_zip = $extract_zip->open('New.zip'); if ($open_zip === TRUE)   $extract_to = getcwd();  $extract_zip->extractTo($extract_to); //extract to the current working directory.  echo "Number of Files to be Extracted:" . $extract_zip->numFiles . "
  ";  $extract_zip->close();  echo 'Files Successfully Extracted!'; > else   echo 'Cannot Extract!'; > ?> 

  The above code will extract the New.zip file created in the first example.

  How to Use PHP Zip Extension to Get Information of All the Member Files of a ZIP

  The PHP ZIP extension can get the information of all the files inside a ZIP .

  php $zip_file = zip_open("New.zip"); if ($zip_file)   while ($zip_members = zip_read($zip_file))   echo "Name of the file: " . zip_entry_name($zip_members) . "
  ";  echo "Original Size of the File: " . zip_entry_filesize($zip_members) . "
  ";  echo "Compressed Size of the File: " . zip_entry_compressedsize($zip_members) . "
  ";  echo "Method of Compression: " . zip_entry_compressionmethod($zip_members) . "
  ";   if (zip_entry_open($zip_file, $zip_members, "r"))   echo "Content of the file:
  ";  $buf = zip_entry_read($zip_members, zip_entry_filesize($zip_members));  echo "$buf 
  ";   zip_entry_close($zip_members);  >  echo "
  ";  >  zip_close($zip_file); > ?> 

  The code above uses built-in ZIP functions to get the information of files inside a ZIP .

  Name of the file: file1 1644842283.txt Original Size of the File: 45 Compressed Size of the File: 39 Method of Compression: deflated Content of the file: #1 This is test file number one.  Name of the file: file2 1644842283.txt Original Size of the File: 45 Compressed Size of the File: 39 Method of Compression: deflated Content of the file: #2 This is test file number two.
