<?php

// This example requires 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 = $zip->NewZip('test.zip');
if ($success != 1) {
    print $zip->LastErrorText . "\n";
    exit;
}

// Create a string array object with our set of filename patterns
// to be excluded:
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringArray')
$sa = new COM("Chilkat.StringArray");
$success = $sa->Append('*.bak');
$success = $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 = 1;
$success = $zip->AppendFiles('/temp/a/*',$recurse);

$success = $zip->WriteZipAndClose();
if ($success != 1) {
    print $zip->LastErrorText . "\n";
    exit;
}

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