Addslashes will have no effect. HTML does not recognize the \ character as
an escape character. That's a PHP concept.

But, you're right that this won't work. htmlentities() by itself will leave
single quotes alone. What you want to use is

htmlentities($string,ENT_QUOTES);

which will convert single and double quotes to entities.
