note 68562 rejected from function.strcmp by bjori

Note Submitter: jeff at skrysak dot com ---- strcmp does not just return -1, 0, or 1. It returns values greater or less than zero, so it may return 14, or -28. It returns a non-zero value if the two strings being compared are not identical, and that non-zero value is the number of characters difference between them. Try this as an example: $difference = strcmp("red", "blue"); echo $difference; The output is: 16 Another example: $difference = strcmp("a", "1"); echo $difference; The output is: -48
