title: Performance: file_get_contents(), Relative and Absolute URLs
body: <p>Is there any performance advantage if I use relative paths as argument in <code>file_get_contents()</code>?</p>
  
  <p><code>file_get_contents("../../mypage.php");</code> </p>
  
  <p><strong>v/s</strong> </p>
  
  <p><code>file_get_contents("http://.../mypage.php");</code></p>
  
  <p>How is <code>file_get_contents()</code> handled internally?</p>
