(PHP Extension) Unzip Files Matching a Pattern (such as *.xml)

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

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// 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 CkHttp();
$success = $http->Download('http://www.example-code.com/data/test.zip','qa_test/test.zip');
if ($success != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

$zip = new CkZip();

$success = $zip->OpenZip('qa_test/test.zip');
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

// Show what's in the .zip by getting the directory as XML.
$zipContentsXml = $zip->getDirectoryAsXML();
if ($zip->get_LastMethodSuccess() != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

print $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>

// ------------------------------------------------------------------------
// If we wish to unzip only .xml files, use "*.xml" for the pattern\
// Unzip to the "qa_output" directory relative to our current working directory.
// (You may unzip to an absolute path by passing an absolute path, such as "/someDir" or
// "C:/someDir", etc.)
// This will unzip only the .xml files.  The relative directory structure within
// the .zip will be created in the local filesystem under the unzip directory
// path passed in the first argument, which in this case is "qa_output".
$count = $zip->UnzipMatching('qa_output','*.xml',true);
if ($count < 0) {
    print $zip->lastErrorText() . "\n";
    exit;
}

// ------------------------------------------------------------------------
// If we wish to unzip only files under the "123" directory, we can do this:
$count = $zip->UnzipMatching('qa_output2','*/123/*',true);
if ($count < 0) {
    print $zip->lastErrorText() . "\n";
    exit;
}

print 'unzipped ' . $count . ' matching file(s).' . "\n";

// ------------------------------------------------------------------------
// If no asterisk character is used, then the match must be exact.
// For example, to unzip "test/hamlet.xml" we must pass the exact path
// as it is in the .zip.  We cannot just pass "hamlet.xml".
$count = $zip->UnzipMatching('qa_output3','test/hamlet.xml',true);
if ($count < 0) {
    print $zip->lastErrorText() . "\n";

// ------------------------------------------------------------------------
// If we want to unzip any file named "hamlet.xml" found in any sub-directory...
