What are you trying to achieve? (Expected behavior)

The environment I am running is Windows Server 2008 R2 with IIS 7

I am trying to follow the instructions on the Readme.md file:
https://github.com/facebook/php-webdriver/blob/community/README.md

What do you get instead? (Actual behavior)

"Unable to refresh session list."

and

"Unable to create new session"

How could the issue be reproduced? (Steps to reproduce)

I ran the Selenium server using this method:

CMD > Run-as Administrator

java -jar selenium-server-standalone-3.5.0.jar

The result from the command is:

14:56:56.648 INFO - Selenium build info: version: '3.5.0', revision: '8def36e068'

So I assume everything is running OK. However, when I try to run the http://localhost/example.php file after following the steps in the readme file, I get this error on the browser:

"This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500"

to troubleshoot, I tried to go to the url: http://localhost:4444/wd/hub/

and at the top of the page I saw a red alert saying

"Unable to refresh session list."

the resulting log from the command prompt:

2017-08-23 14:57:05.288:INFO:osjshC.ROOT:qtp405662939-23: org.openqa.selenium.remote.server.WebDriverServlet-28feb3fa: Initialising WebDriverServlet

When I click to create a session, no matter which browser I select, I get "

"Unable to create new session"

the resulting log is:
