title: Get Client Machine Name in PHP
body: <p>This program only returns the client machine name in localhost only</p>
  
  <p><code>echo gethostbyaddr($_SERVER['REMOTE_ADDR']);</code></p>
  
  <p>If it is run from an online server, then computer name is not shown and some other information is being shown.
  So is there anyway to get the computer name in php when the program runs from online server.</p>
