// 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 = $zip->OpenZip('qa_data/zips/test.zip');
if ($success == 0) {
    print $zip->LastErrorText . "\n";
    exit;
}

// Iterate of each entry in the zip.
// An entry can be a file or directory entry.  For each file, unzip to a byte array.
$numEntries = $zip->NumEntries;
print 'NumEntries = ' . $numEntries . "\n";
$i = 0;
while ($i < $numEntries) {
    // entry is a Chilkat.ZipEntry
    $entry = $zip->GetEntryByIndex($i);
    if ($entry->IsDirectory == 0) {
        $fileData = $entry->Inflate();
        // Do whatever you wish with the file data...
    }

    $i = $i + 1;

$zip->CloseZip();
