Create ZIP Archive with Directory

This section provides a tutorial example on how to create a ZIP archive with a directory and adds files to that directory using the ZipArchive class.

If you want create a directory structure inside the ZIP archive so that files can be added to the archive to different locations, you need to two methods from the ZipArchive class:

1. Create directory inside ZIP archive using addEmptyDir() method. For example, the following code creates a directory and a sub-directory.

$zip->addEmptyDir('src');
$zip->addEmptyDir('src/gif');

2. Add file to archive with local path name using addFile() method. For example, the following code adds 'dot.gif' to the 'src/gif' sub-directory in the archive.

$zip->addFile('dot.gif', 'src/gif/dot.gif');

Here is an example script that creates a new ZIP archive with a directory and adds some files to that directory in the archive.

<?php
#  zip-with-directory.php
#- Copyright 2009 (c) HerongYang.com. All Rights Reserved.

  $zip = new ZipArchive;
  echo "Creating test.zip:\n";
  $rc = $zip->open('/tmp/test.zip',ZipArchive::CREATE);
  if ($rc === TRUE) {
    echo "   test.zip opened\n";

    $dir = "srcDir";
    if ($zip->addEmptyDir($dir) === TRUE) {
      echo "   $dir added\n";
    } else {
      echo "   Failed to add $dir.\n";
    }

    $file = 'dot.gif';
    if ($zip->addFile($file, "$dir/$file") === TRUE) {
      echo "   $file added\n";
    } else {
      echo "   Failed to add $file.\n";
    }

    $file = 'zip-create-new.php';
    if ($zip->addFile($file, "$dir/$file") === TRUE) {
      echo "   $file added\n";
    } else {
      echo "   Failed to add $file.\n";
    }

    $zip->close();
  } else {
    echo "   Failed to create test.zip with error: $rc\n";
  }
?>

Let's try it:

herong$ php zip-with-directory.php
Creating test.zip:
   test.zip opened
   srcDir added
   dot.gif added
   zip-create-new.php added

herong$ unzip -l /tmp/test.zip
Archive:  /tmp/test.zip
