title: php imagettftext letter spacing
body: <p>Does anybody have a function that draws a ttf string (imagettftext) with specified letter spacing?</p>
  
  <p>I cannot find any build-in GD function so I think that it should be done letter by letter adding some constant width.</p>
  
  <p>Maybe someone have such function already :)</p>
  
  <p>ps. the best font will be arial.ttf</p>
