Filter out HTML code from String Login or Register to Bookmark this snippet

Description PHP

This function filters out ALL tags! Does not remove text between tags (ie: <p>this text is not removed</p>) So, any <style> tags would be removed, but the css inside them would remain. something to keep in mind.
