note 91868 added to function.chr

The function chr() also accepts negative numbers as an ascii code, so chr(-number) is equal to chr((number%256)+256). And for ascii code higher than 255 is chr(number%256) We can test with a little script <?php for($i=-300; $i<300; $i++){ echo "Ascii $i\t" . ord(chr($i)) . "\n"; } ---- Server IP: 69.147.83.197 Probable Submitter: 190.71.35.106 (proxied: 200.110.100.195) ---- Manual Page -- http://www.php.net/manual/en/function.chr.php Edit -- https://master.php.net/note/edit/91868 Del: integrated -- https://master.php.net/note/delete/91868/integrated Del: useless -- https://master.php.net/note/delete/91868/useless Del: bad code -- https://master.php.net/note/delete/91868/bad+code Del: spam -- https://master.php.net/note/delete/91868/spam Del: non-english -- https://master.php.net/note/delete/91868/non-english Del: in docs -- https://master.php.net/note/delete/91868/in+docs Del: other reasons-- https://master.php.net/note/delete/91868 Reject -- https://master.php.net/note/reject/91868 Search -- https://master.php.net/manage/user-notes.php
