Good idea. Even better would be in that system() call:

system('nice -10 minizip -o -9 pdfs.zip '.$files);

The 'nice' command causes the task to be run in 'nice' mode at
a lower priority so that it doesn't interfere with other more
important functions being performed by the server.

Appending ' &' to the command may also force it to run in the
background so your php script doesn't have to wait for it to
complete:
system('nice -10 minizip -o -9 pdfs.zip '.$files.' &');
....but I am unsure if that will work.
