note 95046 added to function.substr

For anyone moving code between Windows and Linux I thought this would be worth highlighting. As mentioned in the documentation above: If start parameter is negative, the returned string will start at the start 'th character from the end of string . However, there is different behavior between Windows and Linux in my experience. Take this code as an example: <?php echo substr('abcdef', -7); ?> Windows will print: abcdef Linux will print nothing It seems ridiculous that this scenario would ever happen, but I ran into this problem when working with the mcrypt() functions and variable length key sizes and such. Better written code on my part solved my problem but I thought I should at least contribute my experience. ---- Server IP: 69.147.83.197 Probable Submitter: 64.128.124.130 ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- https://master.php.net/note/edit/95046 Del: integrated -- https://master.php.net/note/delete/95046/integrated Del: useless -- https://master.php.net/note/delete/95046/useless Del: bad code -- https://master.php.net/note/delete/95046/bad+code Del: spam -- https://master.php.net/note/delete/95046/spam Del: non-english -- https://master.php.net/note/delete/95046/non-english Del: in docs -- https://master.php.net/note/delete/95046/in+docs Del: other reasons-- https://master.php.net/note/delete/95046 Reject -- https://master.php.net/note/reject/95046 Search -- https://master.php.net/manage/user-notes.php
