∟Create New ZIP Archive

This section provides a tutorial example on how to create a new ZIP archive and add files into the archive using the ZipArchive class.

The best way to create a new ZIP archive is to use the "ZipArchive::CREATE" flag in the $zip->open() method. For example, the following code will create a new empty ZIP archive, if '/tmp/test.zip' does not exist. If '/tmp/test.zip' exists, it will be open to add new entries or extract entries. It fails only if '/tmp/test.zip' exists and is not a ZIP file.

$zip = new ZipArchive;
$zip->open('/tmp/test.zip',ZipArchive::CREATE);

Here is an example script that create a new ZIP archive and adds some files into the archive.

<?php
#  zip-create-new.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";

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

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

    $file = 'junk.jnk';
    if ($zip->addFile($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-create-new.php
Creating test.zip:
   test.zip opened
   dot.gif added
   zip-create-new.php added
   Failed to add junk.jnk.

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