note 102190 added to function.strspn

very dificult to get from the definition directly, while i search for that,i came to know that strspn() will tell you the length of a string consisting entirely of the set of characters in accept set. That is, it starts walking down str until it finds a character that is not in the set (that is, a character that is not to be accepted), and returns the length of the string so far. and strcspn() works much the same way, except that it walks down str until it finds a character in the reject set (that is, a character that is to be rejected.) It then returns the length of the string so far. $acceptSet = "aeiou"; $rejectSet = "y"; $str1 ="a banana"; $str2 ="the bolivian navy on manuvers in the south pacific"; echo $n = strspn($str1,$acceptSet);// $n == 1, just "a" echo $n = strcspn($str2,$rejectSet);// n = 16, "the bolivian nav" hope this example will help in understanding the concept of strspn() and strcspn(). ---- Server IP: 69.147.83.197 Probable Submitter: 115.186.139.179 ---- Manual Page -- http://www.php.net/manual/en/function.strspn.php Edit -- https://master.php.net/note/edit/102190 Del: integrated -- https://master.php.net/note/delete/102190/integrated Del: useless -- https://master.php.net/note/delete/102190/useless Del: bad code -- https://master.php.net/note/delete/102190/bad+code Del: spam -- https://master.php.net/note/delete/102190/spam Del: non-english -- https://master.php.net/note/delete/102190/non-english Del: in docs -- https://master.php.net/note/delete/102190/in+docs Del: other reasons-- https://master.php.net/note/delete/102190 Reject -- https://master.php.net/note/reject/102190 Search -- https://master.php.net/manage/user-notes.php
