To your earlier reply, yes, I excpected trim to use the standard
charlist when passed with the value null as charlist.
I think at least there should be some kind of warning or notice that
trim will strip away nothing when passed with the charlist=null

In any case, we're not changing the behaviour at this point.
The function is clearly documented expecting a string as the charlist
parameter.

If I understood correctly, you want to be able to do 'trim($foo)' but
by passing 'trim($foo, null)'?

Description:
------------
The trim function doesn't trim away whitespaces when giving it null
value in the charlist.
Reproduce code:
---------------
function array_trim($arr, $charlist=null)
{
if (is_array($arr))
{
foreach($arr as $key => $value)
{
if (is_array($value)) $result[$key] = array_trim($value,
$charlist);
else $result[$key] = trim($value, $charlist);
}
return $result;
}
}
var_dump(array_trim(array(' foo', 'bar ')));
Expected result:
----------------
array(2) {
[0]=>
string(3) "foo"
[1]=>
string(3) "bar"
}
Actual result:
--------------
array(2) {
[0]=>
string(4) " foo"
[1]=>
string(4) "bar "
}
