phpmyadmin prompts when installing: Warning: require_once/libraries/commonincphp error solution

A simpler method: create a new directory, copy the files in phpmyadmin to this directory, and set the path in iis.

After installing PHPmyAdmin, the following error will appear when accessing it in IE:
Warning: require_once(./libraries/common.inc.php) [function.require-once]: failed to open stream: No such file or directory in in
After a while of debugging, I finally found the solution:
It turns out that the upper-level directory permissions of the phpmyadmin installation directory are not enough. Then add the "read and run" permissions of the IIS anonymous User to the upper-level directory, and then open the phpmyadmin page. Success!
[Notes]:
Do not unzip and install phpmyadmin in the root directory, because anonymous users will have root directory permissions.

The above introduces the solution to the error prompt when phpmyadmin is installed: Warning: require_once/libraries/commonincphp, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
