note 94232 added to language.operators.logical

Another example that might help. <?php (isset($panelemail) && !empty($panelemail) ? $panelemail : $userdata['email']); ?> returns the userdata email address, but this <?php (isset($panelemail) AND !empty($panelemail) ? $panelemail : $userdata['email']); ?> returns false. The reason is that the two types of ands have a different order of precedence. "&&" is higher than "AND", and the "?:" operator just happens to come between the two. Also, since "||" (or) is actually higher than "AND," you should never mix &&s and ||s with ANDs and ORs without paretheses. For example: <?php true && false || false ?> returns false, but <?php true AND false || false ?> returns true. ---- Server IP: 64.71.164.2 Probable Submitter: 24.153.133.114 ---- Manual Page -- http://www.php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/94232 Del: integrated -- https://master.php.net/note/delete/94232/integrated Del: useless -- https://master.php.net/note/delete/94232/useless Del: bad code -- https://master.php.net/note/delete/94232/bad+code Del: spam -- https://master.php.net/note/delete/94232/spam Del: non-english -- https://master.php.net/note/delete/94232/non-english Del: in docs -- https://master.php.net/note/delete/94232/in+docs Del: other reasons-- https://master.php.net/note/delete/94232 Reject -- https://master.php.net/note/reject/94232 Search -- https://master.php.net/manage/user-notes.php
