get the difference string after comparing

[hunt00]

How do i get the different string after compare

1. string1 = this-is-a-test
2. string2 =this-is-a-test-numberOne

how to compare those strings and get the string "numberOne" as the result?

Thanks very much for your help!

It looks like this will do what you want.

$str1 = "this-is-a-test";
$str2 = "this-is-a-test-numberOne";

$result = strcmp($str1,$str2);

switch (TRUE) {
  case ($result < 0):
    $remainder = substr($str2,$result);
    echo "The extra text was: $remainder<br />\n";
    break;
  case ($result > 0):
    $remainder = substr($str1,($result * -1));
    echo "The extra text was: $remainder<br />\n";
    break;
  default:
    echo "Strings were the same, no extra data<br />\n";
}
