Hi,
why php results a parse error on this expression?
if (empty(trim('x'))) echo Hello;
the statement works fine:
$x=trim('x');
if (empty($x)) echo Hello;
it is not really logically.
Regards,
Holger

From the docs for empty():
Note that this is meaningless when used on anything which isn't a
variable; i.e. empty (addslashes ($name)) has
no meaning since it would be checking whether something which isn't a variable is a
variable with a FALSE value.
Maybe I am not so
