I use a directory script called, "phpMyDirectory."  

The developer, I suspect may have abandoned upgrading his project.

Here is a link to the demo of his script.  You can visit the admin section too.  Not many developers are willing to show the admin section of their demo but this developer has.  Refer here  https://www.phpmydirectory.com/demo.html

Here is a link to their documentation page https://phpmydirectory.atlassian.net/wiki/spaces/PMDDOC/overview?mode=global
