// 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 requires the Chilkat API to have been previously unlocked.

$zip = new CkZip();

// To verify a password for a Zip, the Zip must be opened:
$success = $zip->OpenZip('myProtected.zip');
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

// Set the password to be verified:
$zip->put_DecryptPassword('secret');
