note 129994 added to language.operators.comparison

It's worth noting that there can be a difference in the logical operation of shorthand ternary (expr1 ?: expr2) vs the full version (expr1 ? expr1 : expr2). The shorthand style may also offer a slight performance enhancement because the initial expression will only be evaluated once. Example: <?php // my_func() will be called twice here // additionally, my_func() may not return the same value both times! $var = my_func() ? my_func() : false; // my_func() will only be called once here $var = my_func() ?: false; ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.84.18 (proxied: 24.180.65.101) ---- Manual Page -- https://php.net/manual/en/language.operators.comparison.php Edit -- https://main.php.net/note/edit/129994 Del: integrated -- https://main.php.net/note/delete/129994/integrated Del: useless -- https://main.php.net/note/delete/129994/useless Del: bad code -- https://main.php.net/note/delete/129994/bad+code Del: spam -- https://main.php.net/note/delete/129994/spam Del: non-english -- https://main.php.net/note/delete/129994/non-english Del: in docs -- https://main.php.net/note/delete/129994/in+docs Del: other reasons-- https://main.php.net/note/delete/129994 Reject -- https://main.php.net/note/reject/129994 Search -- https://main.php.net/manage/user-notes.php
