No need to review the code. The first hunch I had proved correct. PHP opens with a less-than (left carat, or 'less-than') symbol, as do HTML tags. As a result, the browser interprets both as tags and tries to parse them. Viewing the source of that page upon selection of the PHP or HTML options displays the code as expected. Resolution: str_replace('<','<',str_replace('>','>',$data)); Technically, only the less-than symbols need to be replaced, but you may as well - as Charley Jordan says - Keep It Clean. -- </Daniel P.
