I'm reading that it is a "good idea" to sanitize all data returned in a
HTML form. The book recommends using the mysql_real_escape_string()
function as well as stripslashes() and for some data it also recommends
using htmlentities().

Question now is that the mysql function is only available if I'm
connected to a mysql database.

Is the mysql sanitizing only necessary for data fields that are going to
be used against the database? Or is there a similar function to
sanitize user data that may not be used as part of the sql data?
