Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip 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 requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

$zipPath = 'c:/temp/qa_output/out.zip';

// Initialize the zip object with the path of the .zip to be created.
$zip->NewZip($zipPath);

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

// Also, only append 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 appending files.

// Recursively append to the zip object the paths of the files and directories in a directory tree.
// At this point we are not creating the .zip, nor are we reading the contents of the files.
// We are simply appending references to the files and directories in the local filesystem
// that will get processed when WriteZip is called.

$success = $zip->AppendFiles('c:/temp/files_to_zip',$recurse);
if ($success == 0) {
    print $zip->LastErrorText . "\n";
    exit;
}

$zip->FileName = $zipPath;
$success = $zip->WriteZip();
if ($success == 0) {
