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';
}
