I have done some extensive testing, using the suggestions you and Jim 
provided. In summary, the nesting of "location ~ \.php$" inside 
"location ^~ /phpmyadmin/" does not work. The error logged is:

[error] 50038#0: *7541 FastCGI sent in stderr: "Primary script unknown" 
while reading response header from upstream, client: clientIP, server: 
domain.com, request: "GET /phpMyAdmin/ HTTP/1.1", upstream: 
"fastcgi://unix:/var/run/php-fpm.sock:", host: "domain.com"

No matter what variation I tried[0], that was the repeated result.

However, the nesting of "~ ^/phpMyAdmin/(.*\.php)$" inside "location ^~ 
/phpmyadmin/" does work. With everything else the same, this regular 
expression works. See the current working configuration, making use of 
your nesting advice:

location ^~ /phpmyadmin {
         access_log  off;
         rewrite ^  /phpMyAdmin/ permanent;
}

location /phpMyAdmin {
         root /usr/local/www;
         index index.php index.html;

                 location ~ ^/phpMyAdmin/(.*\.php)$ {
                         root /usr/local/www/;
                         include conf.d/php-fpm;
                 }
}

The included php-fpm[1] file is provided below.

I do not know why your suggested regular expression does not work; 
however, your advice to nest does work. Thank you very much for your 
repeated efforts to help, it is very much appreciated.

I am interested as to why this is more efficient and considered better 
practice than my former configuration[2]? Why the statement: 
"DoNotUseAlias (unless necessary)"? My original working setup[2] got the 
job done with only two location blocks. Your recommendations require 
three and a rewrite. Does this not create more work for the server as 
well as more lines of configuration?

Francis, Jim; thank you both very much for your help.
