Yes to both, and quite easily. All the variables passed in a GET request
(which is what the url is) will automatically be made available in the
$HTTP_GET_VARS associative array. So variable "id" is at
$HTTP_GET_VARS['id']. In addition, if the configuration setting
"register_globals" is turned on, the variable will also be accessible
simply as $id.
So in the script news_story.php, you could write a query string like, for
example:
"SELECT article_text from story_table where id=$id"
or
"SELECT article_text from story_table where id=" .
$HTTP_GET_VARS['id']
