note 94144 added to language.operators.bitwise

Here is an example for bitwise leftrotate and rightrotate. Note that this function works only with decimal numbers - other types can be converted with pack(). <?php function rotate ( $decimal, $bits) { $binary = decbin($decimal); return ( bindec(substr($binary, $bits).substr($binary, 0, $bits)) ); } // Rotate 124 (1111100) to the left with 1 bits echo rotate(124, 1); // = 121 (1111001) // Rotate 124 (1111100) to the right with 3 bits echo rotate(124, -3); // = 79 (1001111) ?> ---- Server IP: 69.147.83.197 Probable Submitter: 80.77.114.168 ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit -- https://master.php.net/note/edit/94144 Del: integrated -- https://master.php.net/note/delete/94144/integrated Del: useless -- https://master.php.net/note/delete/94144/useless Del: bad code -- https://master.php.net/note/delete/94144/bad+code Del: spam -- https://master.php.net/note/delete/94144/spam Del: non-english -- https://master.php.net/note/delete/94144/non-english Del: in docs -- https://master.php.net/note/delete/94144/in+docs Del: other reasons-- https://master.php.net/note/delete/94144 Reject -- https://master.php.net/note/reject/94144 Search -- https://master.php.net/manage/user-notes.php
