If you are worried about leading and trailing whitespace in each element
then just add the 'trim' function

function always_single_digit($v){
// If always each entry always has a single digit number
// you can simply chop off the last as number 4
//trim whitespace first
return substr(trim($v), 0, -1) . '4';
}
