trim'ing

<?
echo 'a'.trim(html_entity_decode('&nbsp;a&nbsp;')).'a';
?>

Shouldn't PHP output aaa? Looking at the documentation for trim I see
that it doesn't support chr(0xA0) (eg. html_entity_decode('&nbsp;')),
but it seems to me like it ought to...

That's what the second parameter to trim() is for. You could do this
instead:

echo 'a'.trim(html_entity_decode('&nbsp;a&nbsp;'), "\xA0").'a';

If I do that, I'll either have to do two trims or readd all the
parameters back in. I say that because...

<?
echo 'a'.trim(' a ',chr(0xA0)).'a';
?>

....has spaces in it.

Hi yawnmoth,

&nbsp; is NOT something that is encoded/decoded.

htmlentities is a function that will make sure ALL possible html-markup
characters will be displayed right in html.
(and decode puts them back)

If you feed &nbsp; to htmlentities you will get only the 'dangerous'
characters encoded, thus the &
so that would result in:
&amp;nbsp;

Bottomline: &nbsp; is just a string to htmlencode and decode. Only the & is
of importance to their functionality.
