Add a Common Root Directory to ZIP Entries Using PathPrefix

See more Zip Examples

This example demonstrates how to use the PathPrefix property to prepend a common directory path to all entries added to a ZIP archive.

The PathPrefix value is prepended to the stored ZIP paths for subsequently added entries.

This is useful when:

  • Creating ZIP archives that extract beneath a single root directory
  • Packaging applications or projects into a named top-level folder
  • Avoiding extraction directly into the current directory
  • Organizing ZIP contents beneath a common parent directory

Suppose the local filesystem contains:

c:/MyProject/src/main.cpp
c:/MyProject/src/util.cpp
c:/MyProject/docs/readme.txt

And suppose the following code is executed:

zip.PathPrefix = "MyProject/";

Then the ZIP archive will contain:

MyProject/src/main.cpp
MyProject/src/util.cpp
MyProject/docs/readme.txt

Without a PathPrefix, the ZIP archive would instead contain:

src/main.cpp
src/util.cpp
docs/readme.txt

The PathPrefix is applied only to entries added after the property is set.

<?php

use Chilkat2\Zip;

$zip = new Zip();

// Create a new ZIP archive.
try {
    $zip->NewZip('MyProject.zip');

    // Prepend "MyProject/" to all subsequently added ZIP entries.
    //
    // This causes all files to extract beneath a top-level
    // directory named "MyProject".
    $zip->PathPrefix = 'MyProject/';

    // Recursively add project files.
    //
    // Because saveExtraPath = false, the stored ZIP paths
    // will normally begin with:
    //
    //     src/
    //     docs/
    //
    // But because PathPrefix = "MyProject/",
    // the final ZIP paths become:
    //
    //     MyProject/src/
    //     MyProject/docs/
    //
    $recurse = true;

    $zip->AppendFiles('c:/MyProject/*', $recurse);

    // Write the ZIP archive and close it.
    $zip->WriteZipAndClose();
