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,
