<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Zip')
$zip = new COM("Chilkat.Zip");

$success = $zip->OpenZip('qa_data/zips/sample.zip');
if ($success != 1) {
    print $zip->LastErrorText . "\n";
    exit;
}

$numEntries = $zip->NumEntries;
$i = 0;

while ($i < $numEntries) {
    // entry is a Chilkat.ZipEntry
    $entry = $zip->GetEntryByIndex($i);
    // Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries. 
    // However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    // An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file. 
    // It usually has a directory name with a trailing slash (/) and zero-length content.
    if ($entry->IsDirectory) {
        print $i . ': ' . $entry->FileName . ' (directory)' . "\n";
    }
    else {
        print $i . ': ' . $entry->FileName . "\n";
    }

    $i = $i + 1;
}

// Sample output:

// 0: aaa/ (directory)
// 1: aaa/pigs.json
// 2: bbb/ (directory)
// 3: bbb/base64Cert.txt
// 4: bbb/sub1/ (directory)
// 5: bbb/sub1/brasil_cert.pem
// 6: bbb/sub2/ (directory)
// 7: bbb/sub2/penguins.gif
// 8: bbb/sub2/starfish.jpg
// 9: hamlet.xml
// 10: hello.pdf
