Executing external program without getting output

Is it possible to execute programs in a PHP script without waiting for
the output and successfully ending the PHP script without ending the
external program too?

Do this:

Create a program that executes the program you want to execute.

Use PHP to execute the first program.

The first program will execute the second one and close itself.

The second one will keep running, but PHP won't know ;) and PHP
ignores that fact and so it finishes and the second program will still
be running :).

Let me guess. If you are not interested in the results, you do not need
them right away. Then your program probably does not have to start right
away either. This situation is ideal for a CRON job. CRON jobs are often
used on web servers for clean-up routines, sending reminder e-mails, etc.
