None of this makes any sense. PHP is a server-side request-based
language. If you want to put a delay in between things on a request,
call sleep(), but it is still just a single request which is going to
take a finite amount of time to run.
The correct way to send a bunch of emails is to queue them in your MTA
and have your MTA do efficient grouping and delivery of the messages.
Use the right tool for the job.
