Note Submitter: XZero ---- Re:Dmitry Mazur [quote]strspn will return an zero-based index of a first non-allowed character.[/quote] That's incorrect. As noted above in the documentation and below in barry's note, strspn returns the length of the longest substring in $str1 consisting exclusively of characters from $str2. If strspn returned the index of the first non-allowed character, then Example #1 in the documentation should not return 2, since it starts searching from the first _allowed_ character. Had the $start and $length parameters been omitted, the code would still return 2 (not 0, as it would be if you were correct), since the length of the longest substring of "foo" containing only the letter "o" is 2.
