title: PHP Write to file on different server
body: <p>I need to write to a file that is located on a different server using php. </p>
  
  <p>So, I get user data from a form on one server, and then need to write to a text file that is located on another server. Do I need to authenticate or something similar?</p>
  
  <p>The second server that I need to write to is a windows server. Is this an issue?</p>
  
  <p>Thanks!</p>
