In addition to the certificate issue, Apache also throws an error on architecture, the mismatch of PHP Mach-0 and ARM-64. So, web pages fail. Where can a PHP for ARM 64 be found? Thank you, Harry

Removing Homebrew then doing a fresh install created the appropriate structure (/opt/Homebrew) did the trick. I'm cleaning up some other loose ends but all pieces of my website (PHP, MySQL [mariadb] and httpd) are functioning. What an experience. Thank you for your help, I greatly appreciate it.

Sorry for the duplicate - I need to figure out how to close this out. Removing Homebrew then doing a fresh install created the appropriate structure on my M1 laptop (/opt/Homebrew) did the trick.Homebrew had been using the /usr/ based structure, and therefore the software for Intel architecture.
