title: Convert php string to image
body: <p>I want to convert a php string to an image.
  I use this code</p>
  
  <pre><code>header("Content-type: image/png");
  $string = '.the_title().';
  
  $font  = 5;
  $width  = imagefontwidth($font) * strlen($string);
  $height = imagefontheight($font);
  
  $image = imagecreatetruecolor ($width,$height);
  $white = imagecolorallocate ($image,255,255,255);
  $black = imagecolorallocate ($image,0,0,0);
  imagefill($image,0,0,$white);
  
  imagestring ($image,$font,0,0,$string,$black);
  
  imagepng ($image);
  imagedestroy($image)    
  </code></pre>
  
  <p>but its shows the_title as text instead of executing the string</p>
