note 24568 added to language.operators.bitwise

This functions can be used for rotating the bits of an integer value(32-bit). There are operators for that in C/C++(<<< and >>>). // Rotates $a, $b times to the left function RotateLeft($a, $b){ $s = $a << $b; $c = $a >> (32 - $b); $s = $s | $c; return intval($s); } // Rotates $a, $b times to the right function RotateRight($a, $b){ $s = $a >> $b; $c = $a << (32 - $b); $s = $s | $c; return intval($s); } //Exapmle: RotateRight(13, 68); //returns -805306368 RotateRight(13, 31); //returns 26 RotateRight(13, 32); //returns 13 RotateLeft(13, 68); //returns 208 RotateLeft(13, 31); //returns -2147483642 RotateLeft(13, 32); //returns 13 -- http://www.php.net/manual/en/language.operators.bitwise.php http://master.php.net/manage/user-notes.php?action=edit+24568 http://master.php.net/manage/user-notes.php?action=delete+24568 http://master.php.net/manage/user-notes.php?action=reject+24568
