What can I call to "sterilize" text?

[JFlame]

I have a field that is taking user input as text.  What function can I call in order to remove all HTML tags from this input? 

For example, if the user for some reason enters "<tr><td>A cell!</td></tr>" I'd like it to only save the words, "A cell!".

Hi, for that you can use strip_tags()

Thanks, that works perfectly.
