PHP Requires Chilkat v11.0.0+

Extract a Single ZIP Entry While Preserving Its Stored Path

See more Zip Examples

This example demonstrates how to use the ZipEntry.Extract method to extract a single entry from a ZIP archive.

The example first creates a ZIP archive containing a text file. It then re-opens the ZIP, finds the entry, and extracts it to a base directory.

The Extract method uses the relative path stored within the ZIP entry. Any required subdirectories are created automatically beneath the specified base directory.

    // Add a small text file from memory.
    $zip->AddString('myApp/docs/hello.txt', 'Hello from a ZIP entry!', 'utf-8');

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