title: loadHTML - Pull only headers to retrieve meta?
body: <p>I am using a function with loadHTML($url) to retrieve meta tags from my other site.</p>
  
  <p>It works but page load times increase by 4-5 seconds.</p>
  
  <p>The target pages are bit heavy, Is it possible to load just the header of remote ?</p>
  
  <p>or is there any alternative ?</p>
