note 109325 added to language.operators.precedence

Beware the unusual order of bit-wise operators and comparison operators, this has often lead to bugs in my experience. For instance: <?php if ( $flags & MASK == 1) do_something(); ?> will not do what you might expect from other languages. Use <?php if (($flags & MASK) == 1) do_something(); ?> in PHP instead. ---- Server IP: 69.147.83.197 Probable Submitter: 77.184.58.130 ---- Manual Page -- http://www.php.net/manual/en/language.operators.precedence.php Edit -- https://master.php.net/note/edit/109325 Del: integrated -- https://master.php.net/note/delete/109325/integrated Del: useless -- https://master.php.net/note/delete/109325/useless Del: bad code -- https://master.php.net/note/delete/109325/bad+code Del: spam -- https://master.php.net/note/delete/109325/spam Del: non-english -- https://master.php.net/note/delete/109325/non-english Del: in docs -- https://master.php.net/note/delete/109325/in+docs Del: other reasons-- https://master.php.net/note/delete/109325 Reject -- https://master.php.net/note/reject/109325 Search -- https://master.php.net/manage/user-notes.php
