PHP Bug Type: Scripting Engine problem
Bug description: empty("0") returns true
We've got this little snippet here that in version 3 works properly, however in php4 it has a
minor problem. For all $rIA1 values other than 0 it works fine, but when $rIA1==0, empty returns
true.
// $rIA1 is between 0 and 4
$rIA1=0;
if (empty($rIA1)) {
$filled = 0;
echo "Please answer question: IA1 <br> ";
}
//Result
Please answer the question: IA1
