you can test for undefined variables using
isset($var)
or
empty($var)
look into the php manual for more details on these functions
yes php does provide you with an option to create variables from variables
themselves
refer to the following

Not sure if this is hat you are looking for, but I do something similiar in
my script. Its set up so that the action of the script depends on whether
or not the ASIN was passed in..
if(isset($asin))
{
$mode='save_info';
}
that way if something like: "book_reviews.php?asin=000129091" is called,
