The third optional parameter inverses the binary string, eg 101 becomes 010. -- darkshad3 at yahoo dot com */ $bin = decbin($decimal); if ($inverse) { $bin = str_replace("0", "x", $bin); $bin = str_replace("1", "0", $bin); $bin = str_replace("x", "1", $bin); } $total = strlen($bin); $stock = array(); for ($i = 0; $i < $total; $i++) { if ($bin{$i} != 0) { $bin_2 = str_pad($bin{$i}, $total - $i, 0); array_push($stock, bindec($bin_2)); } } $reverse ? rsort($stock):sort($stock); return implode(", ", $stock); } ?> The printed result is : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512 ---- Server IP: 193.190.198.20 Probable Submitter: 62.235.142.39 ---- Manual Page -- http://www.php.net/manual/en/function.decbin.php Edit -- https://master.php.net/note/edit/73282 Del: integrated -- https://master.php.net/note/delete/73282/integrated Del: useless -- https://master.php.net/note/delete/73282/useless Del: bad code -- https://master.php.net/note/delete/73282/bad+code Del: spam -- https://master.php.net/note/delete/73282/spam Del: non-english -- https://master.php.net/note/delete/73282/non-english Del: in docs -- https://master.php.net/note/delete/73282/in+docs Del: other reasons-- https://master.php.net/note/delete/73282 Reject -- https://master.php.net/note/reject/73282 Search -- https://master.php.net/manage/user-notes.php
