note 61415 added to language.operators.bitwise

Bitwise operators are swell, but (a & b & c & d) == a is not a way to test for four-way equality. If a is zero, it'll always be true, and in general it will be true any time a has no bits not also in the other three values. ---- Server IP: 64.71.164.2 Probable Submitter: 208.31.42.47 ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61415 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61415&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61415&report=yes Search -- http://master.php.net/manage/user-notes.php
