title: PHP's file_exists() will not work for me?
body: <p>For some reason this PHP code below will not work, I can not figure it out.</p>
  
  <p>It is very strange, 
  file_exists does not seem to see that the image does exist, I have checked to make sure a good file path is being inserted into the file_exists function and it is still acting up</p>
  
  <p>If I change file_exists to !file_exists it will return an images that exist and ones that do not exist</p>
  
  <pre><code>define('SITE_PATH2', 'http://localhost/');
  
  $noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg';
  $thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
  if (file_exists($thumb_name)) {
      $img_name = $thumb_name;
  }else{
      $img_name = $noimg;
  }
  echo $img_name;
  </code></pre>
