title: Intergrating wordpress blog in core php site
body: <p>I have a site in core php (<code>www.example.com</code>). I created the <code>/blogs</code> directory and installed wordpress in it. 
  <code>www.example.com</code> has it own login system. In my <code>www.example.com/blogs</code> has many blogs and users will come from <code>www.example.com</code> . I need to access logged in user info in <code>www.example.com/blog</code>s page. So that user dont have to login again in <code>www.example/blogs</code> to comment on article. How to do this? Do i need to make custom plugin for this task ?</p>
