note 73713 added to language.operators.bitwise

To create your own function using a $mode variable, you'd do something like the following: <?php define("MODE1",1); // 2^0 define("MODE2",2); // 2^1 define("MODE3",4); // 2^2 define("MODE4",8); // 2^3 function test($mode) { if($mode & MODE1) { echo "MODE 1 "; } else if($mode & MODE2) { echo "MODE 2 "; } else if($mode & MODE3) { echo "MODE 3 "; } else if($mode & MODE4) { echo "MODE 4 "; } } test(MODE1 | MODE2 | MODE4); ?> Outputs: "MODE 1 MODE 2 MODE 4" It could be further extended to use more variables, using 2^4, 2^5, and so on. ---- Server IP: 69.147.83.197 Probable Submitter: 68.98.248.145 ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit -- https://master.php.net/note/edit/73713 Del: integrated -- https://master.php.net/note/delete/73713/integrated Del: useless -- https://master.php.net/note/delete/73713/useless Del: bad code -- https://master.php.net/note/delete/73713/bad+code Del: spam -- https://master.php.net/note/delete/73713/spam Del: non-english -- https://master.php.net/note/delete/73713/non-english Del: in docs -- https://master.php.net/note/delete/73713/in+docs Del: other reasons-- https://master.php.net/note/delete/73713 Reject -- https://master.php.net/note/reject/73713 Search -- https://master.php.net/manage/user-notes.php
