Hi Loïc !

I'm back from holiday and have read about 140 messages in 
the list (ouch!).

Why do you write '& quot;' and not '"' ? Is that inserted 
space necessary ?

Really ? I mean if you have a form with <input name="foo" value="""> 
and press submit, you'll get $foo='"' (modulo magic quotes of 
course) in your script (and not $foo='"'), which should 
not cause any problem...

I'd just like to understand a bit more. Maybe $fields_prev[] 
solves problems that such a basic example may not show. Is 
$fields_prev[] intended to handle only basic html special 
chars ('<', '>', '"', '&'), or also other special chars ?
