Windows - Issues related to content changes in php monitoring folders

I want to monitor the filemtime of a folder every 5 seconds, and then realize its function by comparing the similarities and differences of the filemtime twice. $filetime1 = filemtime("PATH.txt");sleep(10);$filetime2 = filemtime("Path.txt"), but in the end, the time obtained by the two filemtimes are the same, I just want I would like to ask if there is any function that can realize its real-time monitoring function. I am using a Windows system. Is there a scheduled task method similar to Linux's crontab on Windows?
