"$question[$i]" will print literally 'array[1]', not '100' like you
intended. If you want it to work, you gotta denote the array reference with
curly braces:
echo "<input type='checkbox' name='{$question[$i]}'> This is the...."
Now you'll get '100', '125', etc, which gets us to the second problem:
having plain numbers as field names. Well, perhaps it's not a problem, but
it is something I wouldn't do. The only explanation I can offer for this is
"just because". I'd throw in some alphabets, just in case, name them 'q100',
'q125', etc...

Here you reference correctly the field names 100, 125, etc.. but the reason
they are not found is the fields are actually named array[0]..., like I
explained earlier...
