Couple of questions first.

1) From your example it looks like the comma separated values. it this
the case were every value ends with a number?

2) Do the you want and NON-4 numeric value !=2 and make it 4?

3) Will the numeric values only be a single digit like 3 and !>9 like 15?

4) Do you need the result to be a single string or are you using this in
an array?

If I assume you have a CVA string and you want to change any single
digit trialling number !=4 to be 4 and you need to have it back as
single CSV string then one way.

Depends on your conditions

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';
}

function optional_multidigit($v){
// Change if trailing one or more digit number
return preg_replace('/\d+$/', '4', $v);
}

function only_if_2($v){
// Change only if trailing digit is 2
return preg_replace('/2$/', '4', $v);
}

$before="arts color bb 4, tested well 4, passenger 2, arrived 2, not_two
5, multidigit 12";

$a=explode(',', $before);

print "String before: $before\n";

print 'Only single digit: ' . implode(',',
array_map("always_single_digit", $a)) . "\n";

print 'Possibly multidigit: ' . implode(',',
array_map("optional_multidigit", $a)). "\n";

print 'Only if #2: ' . implode(',', array_map("only_if_2", $a)). "\n";

Take care,
