note 102205 added to function.sprintf

If you want to convert a decimal (integer) number into constant length binary number in lets say 9 bits, use this: $binary = sprintf('%08b', $number ); for example: <?php $bin = sprintf('%08b',511 ); echo $bin."\n"; ?> would output 111111111 And 2 would output 00000010 I know the leading zeros are useful to me, perhaps they are to someone else too. ---- Server IP: 69.147.83.197 Probable Submitter: 109.226.18.250 ---- Manual Page -- http://www.php.net/manual/en/function.sprintf.php Edit -- https://master.php.net/note/edit/102205 Del: integrated -- https://master.php.net/note/delete/102205/integrated Del: useless -- https://master.php.net/note/delete/102205/useless Del: bad code -- https://master.php.net/note/delete/102205/bad+code Del: spam -- https://master.php.net/note/delete/102205/spam Del: non-english -- https://master.php.net/note/delete/102205/non-english Del: in docs -- https://master.php.net/note/delete/102205/in+docs Del: other reasons-- https://master.php.net/note/delete/102205 Reject -- https://master.php.net/note/reject/102205 Search -- https://master.php.net/manage/user-notes.php
