I used XAMPP to install Apache, PHP, MySQL.
I then personalized the c:\\xampp\\apache\\conf\\httpd.conf
file thusly:
# DocumentRoot \"C:
This may help others You will find the lines in your httpd.conf file
# XAMPP specific settings
Include "conf/extra/httpd-xampp.conf"
If you look in the included file "httpd-xampp.conf" you will see the line
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
AllowOverride AuthConfig Require all granted
Modifying this information in any number of ways (change httpd-xampp.conf, include your own custom conf file, placing a statement after the above statements) should solve your problem
