Then the simplest is what I offered with function always_single_digit() 
where you just chop off the last character and then replace with '4'.

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

//your sample
$str="aaa 4,aafagagsg 4,afgsgfs 2,a affs 4,aa adfdf 2 afsf ercrrt s 4";
//split into array on ','
$arry=explode(',', $str);
//use array_map to use callback in each element to replace with 4
print implode(',', array_map("always_single_digit", $arry));
