note 78410 added to function.substr

Just want to note that if you are retrieving sub-strings of length zero, this function breaks in the base case (the source being an empty string): substr('123',0,0) returns string(0) "" substr('12',0,0) returns string(0) "" substr('1',0,0) returns string(0) "" but substr('',0,0) returns bool(false) Although this is the documented behavior, I would consider it unexpected in many circumstances. ---- Server IP: 69.147.83.197 Probable Submitter: 72.8.117.17 ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- https://master.php.net/note/edit/78410 Del: integrated -- https://master.php.net/note/delete/78410/integrated Del: useless -- https://master.php.net/note/delete/78410/useless Del: bad code -- https://master.php.net/note/delete/78410/bad+code Del: spam -- https://master.php.net/note/delete/78410/spam Del: non-english -- https://master.php.net/note/delete/78410/non-english Del: in docs -- https://master.php.net/note/delete/78410/in+docs Del: other reasons-- https://master.php.net/note/delete/78410 Reject -- https://master.php.net/note/reject/78410 Search -- https://master.php.net/manage/user-notes.php
