mmm... yeah... That's what I had before
(acutally I was using the alias split)...
it does NOT however preserve the areas
of white space.
Instead the target of:
> > $wordsarr = ('This',' ','contans','
> > ','white',' ','space',' ','.')
You get:
> > $wordsarr =
> > ('This','','contans','','white','space','','.')
which has totally destroyed the whitespace I'm trying to
keep intacted.
I'm starting to wonder if maybe preg_match_all is better
suited for something like this... just no idea how to do
the regex that matches words & spaces and populates them
into the array.
maybe something like: echo preg_match_all("|(\s+)?(.*)?(\s+)?|",$test,$arr);
sigh... I dunno regex.
