Unzip Files in a Date Range

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to unzip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

<?php

$success = 0;

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

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

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

// The MinDate and MaxDate properties use the timestamp date/time string format.
// Here are some examples:
// YYYY-MM-DD (e.g., 2024-07-31)
// YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
// 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

// Only unzip files having a last-modified date greater than 1-Jan-2017
$zip->MinDate = '2017-01-01T00:00:00Z';

// Also, only unzip files having a last-modified date less than the end of 2020
$zip->MaxDate = '2020-12-31T23:59:59Z';

// You don't need to specify both MinDate and MaxDate.
// You can specify only one or the other if needed.

// The MinDate/MaxDate properties apply to all of the Chilkat methods for unzipping.

$numUnzipped = $zip->Unzip('c:/temp/unzipDir');
if ($numUnzipped < 0) {
    print $zip->LastErrorText . "\n";
