There would be nothing. All data will be potentially dangerous when inserting it into such things as MySQL statements. Therefore all programmers need to up their game a little when they remove it as they'll be no more babysitting!

Don't worry, TalkPHP will have this covered addslashes is a good function to start at, but there's also mysql_real_escape_string, too. Although I hear they're removing addslashes from PHP 6. Not that I use it, personally.
