MariaDB has worked fine but is now failing to run on boot up. I have uninstalled and it then reinstalled it and this does not fix anything.
Here is the output from mysql.server.start
mysql.server start

ERROR!
This is what I get from brew info mariadb
mariadb: stable 10.6.4 (bottled)
Drop-in replacement for MySQL
https://mariadb.org/
Conflicts with:
mariadb-connector-c (because both install `mariadb_config`)
mysql (because mariadb, mysql, and percona install the same binaries)
mytop (because both install `mytop` binaries)

==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.
MySQL is configured to only allow connections from localhost by default
To have launchd start mariadb now and restart at login:
brew services start mariadb
Or, if you don't want/need a background service you can just run:
mysql.server start

The mac is serving up PHP successfully which throws a "Connection Refused" error when the code tries to talk to the database. So, I don't really understand the httpd error if apache appears to be operating.
Here is the contents of the err log (thank you DanBlack)

This keeps repeating every few seconds.
However, I can now connect to the localhost mysql server and run things using mysql databases @ 127.0.0.1 having deleted /usr/local/var/mysql/ib_logfile0
