Description:
------------
If the start value is lower then the max value, you should get one result even if the step makes it unable to return 2 values. 

Instead of 
$list = range($i * 2, TOP, $i);

I have to write
if (TOP > ($i * 3))
        $list = range($i * 2, TOP, $i);
    else 
        $list = array($i * 2);

could not even use
$list = @range($i * 2, TOP, $i) or array($i * 2);

Reproduce code:
---------------
print_r(range(6, 8, 3));

Expected result:
----------------
Array
(
    [0] => 6
)

Actual result:
--------------
Warning: range(): step exceeds the specified range
