title: How can I access windows services or data from windows machine from my website using PHP?
body: <p>This is about Implementation of single sign on in PHP.</p>
  
  <blockquote>
    <p>I have a website say abc.com, I want to check, is user logged into
    his/her outlook mail? Means I want to get email address of the user
    from his local machine by using website to implement Single sign-in on
    web.</p>
    
    <p>Or you can say I want to check user profile (email-id which one used on windows machine to get access windows applications)</p>
  </blockquote>
  
  <p>May be there is another workaround for this like if user is using window system &amp; he is logged into the outlook its mean any specific website, link or api will return some flag etc. </p>
