note 65226 added to language.operators.bitwise

For the sake of completeness I want to note that a check for equality doesn't have so long winded as in the (wrong) example below. Because of simple laws of logic you don't have to check every possible combination of the variables. The following code will be no surprise for most of you, but for some people it could be helpful. -Tim <?php $a = 42 ; $b = 42 ; $c = 1138 ; $d = 1701 ; echo $a==$b && $b==$c && $c==$d ? "equal" : "not equal" ; // echoes not equal $a = 42 ; $b = 42 ; $c = 42 ; $d = 42 ; echo $a==$b && $b==$c && $c==$d ? "equal" : "not equal" ; // echoes equal ?> ---- Server IP: 217.160.72.57 Probable Submitter: 84.132.197.13 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit -- http://master.php.net/note/edit/65226 Del: integrated -- http://master.php.net/note/delete/65226/integrated Del: useless -- http://master.php.net/note/delete/65226/useless Del: bad code -- http://master.php.net/note/delete/65226/bad+code Del: spam -- http://master.php.net/note/delete/65226/spam Del: non-english -- http://master.php.net/note/delete/65226/non-english Del: in docs -- http://master.php.net/note/delete/65226/in+docs Del: other reasons-- http://master.php.net/note/delete/65226 Reject -- http://master.php.net/note/reject/65226 Search -- http://master.php.net/manage/user-notes.php
