the ? and : thing...

I have code that looks like this:
[hr]
[code=php:0]$result  =  move_uploaded_file($temp_name, $file_path);
  if (!chmod($file_path,0777))
    $message = "change permission to 777 failed.";
  else
    $message = ($result)?"$file_name uploaded successfully." :
              "Something is wrong with uploading a file.";[/code]
[hr]
Just wondering what the ($result)? part is.  My guess is that it's equivalent to the following:
[hr]
[code=php:0]if ($result){
$message = "$file_name uploaded successfully.";
}
else {$message = "Something is wrong with uploading a file."};[/code]
[hr]

Am I on the right track? Can someone elaborate for me as to what this is?

You're right. It's using the ternary operator. Think of it as an "if then else" construct.

Thanks both for the quick replies.

I would've tried to look it up but I wasn't sure of what to call it.
