Question : PHP string replace question

I have very novice php skills and am trying to write an admin page to manage some links that I store in a database (instead of using phpMyAdmin).

I would like to do a little processing when posting as well as retrieving the data to handle the problem of displaying quotes ("). I want to be able to input quotes in the admin and then have them converted to " for storage in the db. And then when the data is retrieved for editing, have it convert " back to ". Is there a really easy way to do this?

Super easy: htmlentities($string)

and to convert it back:html_entity_decode($string)
