Ehhhrrrmmm -- that elseif () condition is always going to be true:
logically, it's got to be not equal to one or other of the values.
>From a quick glance at the code, I'd say just a straight else would do the
job here, thus:
if ($ans_three[$qzid] === 'None of the above'
|| $ans_three[$qzid] === 'All of the above')
{
if ($ans_four[$qzid] === 'None of the above'
|| $ans_four[$qzid] === 'All of the above')
{
$answers = rand(6,8);
}
else
{
$answers = 5;
}
}
else
{
$answers = rand(1,4);
}
