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. ---- Server IP: 208.69.120.35 Probable Submitter: 8.15.142.207 ---- Manual Page -- http://www.php.net/manual/en/function.strspn.php Edit -- https://master.php.net/note/edit/91915 Del: integrated -- https://master.php.net/note/delete/91915/integrated Del: useless -- https://master.php.net/note/delete/91915/useless Del: bad code -- https://master.php.net/note/delete/91915/bad+code Del: spam -- https://master.php.net/note/delete/91915/spam Del: non-english -- https://master.php.net/note/delete/91915/non-english Del: in docs -- https://master.php.net/note/delete/91915/in+docs Del: other reasons-- https://master.php.net/note/delete/91915 Reject -- https://master.php.net/note/reject/91915 Search -- https://master.php.net/manage/user-notes.php
