note 104805 added to function.substr

When using a value of a wrong type as second parameter , substr() does not return FALSE but NULL although the docs say, it should return FALSE on error. Prior to PHP 5.3, substr() tries to cast the second parameter to int and doesn't throw any errors. Since PHP 5.3 a warning is thrown. ---- Server IP: 212.124.37.9 Probable Submitter: 217.66.60.14 ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- https://master.php.net/note/edit/104805 Del: integrated -- https://master.php.net/note/delete/104805/integrated Del: useless -- https://master.php.net/note/delete/104805/useless Del: bad code -- https://master.php.net/note/delete/104805/bad+code Del: spam -- https://master.php.net/note/delete/104805/spam Del: non-english -- https://master.php.net/note/delete/104805/non-english Del: in docs -- https://master.php.net/note/delete/104805/in+docs Del: other reasons-- https://master.php.net/note/delete/104805 Reject -- https://master.php.net/note/reject/104805 Search -- https://master.php.net/manage/user-notes.php
