note 35662 added to language.operators.bitwise

To the poster who wanted more information on bitwise operators in PHP, they tend to be used more in C/C++ or assembly language. However, they can be useful in PHP. One example is where you're using MySQL and have a form with several checkboxes. It's a pain and not very efficient to have a DB containing columns for every one of these checkboxes. So, try compressing the checkbox values into a single variable and therefore a single MySQL column. ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35662 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35662&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35662&report=yes
