Example code to unzip Files Matching a Pattern (such as *.xml) Chilkat2 PHP

<?php

use Chilkat2\Http;
use Chilkat2\Zip;

// This example works with the .zip located at http://www.example-code.com/data/test.zip

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// First, let's download the .zip
$http = new Http();
try {
    $http->Download('http://www.example-code.com/data/test.zip', 'qa_test/test.zip');

    $zip = new Zip();

    $zip->OpenZip('qa_test/test.zip');

    // Show what's in the .zip by getting the directory as XML.
    $zipContentsXml = $zip->GetDirectoryAsXML();
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $zipContentsXml, "\n";

/*
 * In this case, the contents of our .zip look like this:
 * <?xml version="1.0" encoding="utf-8" ?>
 * <zip_contents>
 *     <dir name="test">
 *         <dir name="abc">
 *             <dir name="123">
 *                 <file>ecc_public.pem</file>
 *                 <file>starfish.jpg</file>
 *             </dir>
 *             <file>comodo-certificates.pem</file>
 *             <file>pigs.xml</file>
 *         </dir>
 *         <file>COMODORSACertificationAuthority.crt</file>
 *         <file>hamlet.xml</file>
 *     </dir>
 * </zip_contents>
