Your RegEx is probably fine...
But you are probably missing a closing quote in lines BEFORE line 39, and
PHP thinks everything up the the =====^ is still part of some giant
monster long string that spans multiple lines, and then it gets to the
/head bit (because your opening quote is really a closing quote for
something way earlier) and BAM! /head don't mean nothing useful in PHP...
So all this discussion about security, strip_tags, and suchlike has
nothing to do with your original problem :-)
But, hey, ya learned some stuff, and that's never bad. :-)
