Yes, it'd be really smart to. If any of the data in the serialized string
has a ' or " in it, it could break your query. Or the user being able to
enter a ' or " into the data could open you to SQL attacks.

You want to do addslashes() on the result of serialize(), not the content
going into it, too. PHP will introduct double quotes around any strings that
are serialized. These should be escaped or they could end up breaking your
query.

Note that you don't have to do stripslashes() on the serialized string when
you pull it out.
