make the error.log file role over to a new file at a certain size, and only keep N

make this log file essentially work like standard errorfiles where you end up with errors.log errors.1.log etc, and none of them get too big

This is usually left to some system tool (mostly logrotate). It might be better to write it to the standard SAPI error file instead of a custom one since that is usually handled by the os.

Can you recommend how to implement?

I recently had to do this as my log suddenly became several dozen GBs due to some tomfoolery.
The solution in my case was editing /etc/logrotate.d/apache2 and settings size 100M at the top.

This should be something discussed in the setup documentation so the admin can make a decision appropriate to their needs, rather than us imposing a limit on them.
