Hi,
I've just discovered Rapid PHP.
It generally looks very good, except one immediate bug or oddity.
I often use 'block' echo, like:
echo <<< EOT
<p>multiple lines of html</p>
<etc>
<etc>
EOT;
The hightlighting goes haywire in these blocks, with words in plain text (not just within HTML tags) being picked out as keywords. Also an apostrophe or &#nn; element affects the the rest of the line it's on.
