One place where it finds use is to create a delay.
Lets say you’ve built a crawler that uses
curl/file_get_contentsto get remote pages. Now you don’t want to bombard the remote server with too many requests in short time. So you introduce a delay between consecutive requests.sleeptakes the argument in seconds, its friendusleeptakes arguments in microseconds and is more suitable in some cases.
