Wasn't sure what to put in the title of the queston. I'm a little confused by the following behavior. I'm trying to strip the HTML tags from a variable and save that value to another variable. I have the following code:

$item->{'notag_title'}=&strip_tags($item->{'title'});

sub strip_tags { $_[0]=~s/<[^>]+>//gs; return $_[0]; }

As expected $item->{'notag_title'} becomes a tag-less version of $item->{'title'}. But $item->{'title'} loses its tags too! I don't understand it at all. Is $_[0] a reference to the original variable, not a variable local to the subroutine?
