Spell Check Engine...

I have a content management system written in PHP, and the user wants a Spell Checker built into the HTML forms.  i.e., when she enters text into a text area just like this question I'm entering, she wants to perform a spell check to ensure that the info is spelled correctly.  Does anybody know of an open source spell check API I could plug in for her with relative ease?

Thanks,
Scott.
