使用PHP更改文件夹的创建日期

I could not make it work. I can change the modification time of a file, but with folder nothing happen and function alway return true.

Platform: Windows 10 64bit, PHP 5.5.12

Code:

$sync_from = "c:\\abc";
$sync_to = "d:\\abc";
//In c:\abc have a folder name: folder_a
$link = "d:\\abc\\folder_a";
//Create folder_a in d:\abc
mkdir($link);
//get time of source folder (c:\abc\folder_a)
$time = filemtime(str_replace($sync_to, $sync_from, $link));
//change time of just create folder
if (!touch($link, $time)) echo "Could not change modification time
";

I'm not sure if you're asking for changing the modification date, or asking for the creation date. For modification date of a folder, the following code is working perfectly. Check if you're making some mistake of the time not being set in one of the variables!

<?php

$link = "SomeFolder";

//Set 2 hours back
$time = time() - 7200;

if (touch($link, $time)) {
    return true;
} else {
    return false;
}
?>
