Answer 1

You can try
foreach ( tagReader("4.mp3") as $name => $value ) {
printf("<p>%s:%s</p>", $name, $value);
}

Answer 2

This is because you are returning an array. If you want to print out the contents of the array's elements, you will have to loop through the array and print each element instead of returning the whole array.
Something like:
foreach ($results as $key => $value)
echo $key . " " . $value;
