Will be useful for an upcoming Flash gallery that dynaically loads images. I didn’t want to reinvent the wheel, but apparently I was too impatient to find the wheel. 😛
PHP Code:
$directory_list = ".";
/*   This may pose a security risk, hence commented out:
if( isset($_GET["dir"])) {
   $directory_list = $_GET["dir"];
} else {
   $directory_list = ".";
}
*/
function getExtension($filename)   {
   $file_ext = substr (strrchr ($filename, "."), 1);
   return ($file_ext);
}
if(is_dir($directory_list))   {
   header('Content-Type: application/xml');   //   Set content type for header
//   header("Content-type: text/xml");   //   Both work, not sure which one's most compatible
   echo "\n\n";
   $dir = opendir($directory_list);
   while(false !== ($file = readdir($dir)))   {
      $type   = filetype($directory_list ."/". $file);
      $ext   = strtolower(getExtension($file));   //   must convert ext to lowercase b/c matching below is case sensitive
      if(($ext == "jpg" || $ext == "png" || $ext == "gif") && $type != "dir") {
         $dimensions   = getimagesize($directory_list ."/". $file);
         $file_width   = $dimensions[0];
         $file_height   = $dimensions[1];
           ÂÂ
         $image_node = <<< EOH
  ÂÂ
     ÂÂ$file
     ÂÂ$file_width
     ÂÂ$file_height
  ÂÂ
EOH;
         echo $image_node;
      }
   }
   closedir($dir);
   echo "";
} else {
   echo "Unable to list \"../" . $directory_list . "\".";
}
