<?php

$zip = new COM("Chilkat.Zip2");

//  Any string unlocks the component for the 1st 30-days.
$success = $zip->UnlockComponent('Anything for 30-day trial');
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

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

//  Create a string array object with our set of filename patterns
//  to be excluded:
$sa = new COM("Chilkat.CkStringArray");
$sa->Append('*.bak');
$sa->Append('*.tmp');

//  Tell the zip object to use these exclusions:
$zip->SetExclusions($sa);

//  Append a directory tree.  The AppendFiles does
//  not read the file contents or append them to the zip
//  object in memory.  It simply appends references
//  to the files so that when WriteZip (or WriteZipAndClose,
//  or WriteExe, etc.) is called, the files are compressed
//  and encrypted.
$recurse = true;
$zip->AppendFiles('c:/temp/a/*',$recurse);

$success = $zip->WriteZipAndClose();
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

print 'Zip Created!' . "\n";
