But the var isn't empty. $a[] = 'blah'; $a[] = 'blah'; $a['assoc'] = 'array'; foreach ($a as $k => $v) if ($k == 'assoc') # do something The 'if' statement is incorrectly executing when $k is 0. I find it strange that 0 == any string. The way I see it, 0 is false. false == 'a string' should not be true. Thanks for the reply, -- C > Regards, > Torgny > > Christopher J.
