If what you are trying to do is decode HTML entities and then strip slashes, then yes, it will do that.

Why are slashes in there in the first place?

From your question, what I could infer is you are looking for sanitizing the data in order to escape all special characters and store in db? Assuming that as a situation, If you are using php 5.2 or above look for PHP Filters and Sanitizers.
