使用php脚本在Windows上复制图像而不修改创建日期

I created a small php script to categorize picture by folder/date in Windows. all is working great, files goes to the good place BUT it changes my "created date", wich I want to keep intact.

I use a very simple php copy() function.

I've use the touch() + filectime but still cannot change the creation date of file

any idea ?

from php.net:

It's worth noting that copy() sets the destination file's last modified time/date.

what is the problem of using this?

clearstatcache();
$oldstamp = filemtime("file.txt");
copy("file.txt","newfolder/file.txt");
touch("newfolder/file.txt",$oldstamp);
