Protecting Queries

Since day one of me doing MySQL stuff in PHP, I've always set up my query as a variable then put it into the query function such as this: $query = "SELECT * FROM bobstuff WHERE id='1'"; $result = mysql_query($query, $connection); I've just come aware of the security risks of this. How could I make it so the $query variable isn't editable from the URL? Should I turn register_globals off? Thanks, Stephen Craton http://www.melchior.us "Life is a gift from God.
