I have two strings:
$stringA = "1,2,3,4";
$stringB = "1,2,4,5";
I want to pick out the values from $stringB that are not in $stringA.
How can I do that?

explode() both arrays and use array_diff() to compute differential array.

A:
A combination of explode and array_diff should get you there.
array_diff(explode(',', $stringB), explode(',', $stringA));
How can I display the results in a nice format instead of Array()?

If I understand the question correctly, you have to switch `$stringA` and `$stringB`. I think the OP wants all the values that are not in `$stringA`.

You are right they need to be switched, but how can I echo the results in a nice format instead of Array()?

@John Norton: You could join them again, using `$str = implode(' ', $result);` or loop over the array and print the values.
