title: destroy WordPress PHP session based on PHPSESSID value
body: <p>I have a really limited WordPress knowledge but need to perform a following task - I have to destroy WordPress PHP session based on PHPSESSID value.</p>
  
  <p>I need to handle direct call from another server(CAS server Single Logout (SLO) request) that will POST to my some WP url PHPSESSID value. Based on this PHPSESSID value I need to destroy some user session. Browser is not involved here</p>
  
  <p>Please show me an example how it can be achieved.</p>
