Question

function rawtransform{

            if ($raw>=500 && $raw<=550){
                    $score= 1;
            }
            if ($raw>=550 && $raw<=600){
                    $score= 2;
            }
            if ($raw>=600 && $raw<=650){
                    $score= 3;
            }
            if ($raw>=700 && $raw<=750){
                    $score= 4;
            }
            if ($raw>=750 && $raw<=800){
                    $score= 5;
            }
            if ($raw>=800 && $raw<=850){
                    $score= 6;
            }
            if ($raw>=850 && $raw<=900){
                    $score= 7;
            }
            if ($raw>=900 && $raw<=950){
                    $score= 8;
            }
            if ($raw>=950 && $raw<=1000){
                    $score= 9;
            }
    }

This seems very basic and not very well coded. (I am only learning php )
Can anyone offer a better way of doing this? maybe a single if statement. I think there is a way just cant get my head round it.

Thanks

How about just using math?

function rawtransform($raw) {
  $score = (int)($raw/50)-9;
}

You may want to add a range check for the input, though.
