header location syntax to pass string values to the destination

Could somebody offer more information on how to pass $strings through a header function? In the script I am working on, it is a simple file upload form handled by a PHP script where after the file upload is verified, the user is sent to a success page that should idealy include use of 3 strings ($uploadfile_name, $uploadfile_type and $uploadfile_size). The example I was given by some users of EFNET IRC's #php channel was as follows... header("Location: success.php?uploadfile_name=".$uploadfile_name); However, I could not find any description of the syntax structure to be used in the URL of a header function to include a string or multiple strings to be passed to the location destination page or script.
