The function this is from sometimes uses $_POST or $_GET input, so
sometimes its comparing 1337 with '1337' and === would break that.
so I'll have to use something like:
if (($value == $curval) && !(is_string ($curval) && ($value == 0)))
unless there is a better way

The string is converted to an integer when compared with an integer.
See this link for more info.

Try using === instead.
