note 125830 added to language.operators.logical

In response to Lawrence about || always returning a boolean: Instead of $x ? $x : 'fallback' you can also use the "elvis operator": $x ?: 'fallback' which is useful in cases, where the left-hand side of the ternary operator is too long type, is too complex to calculate twice, or has side-effects. It also combines nicely with the ?? operator, which is equivalent to an empty() check (both isset() and != false): $x->y ?? null ?: 'fallback'; instead of: empty($x->y) ? $x->y : 'fallback' ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.245 (proxied: 185.14.232.154) ---- Manual Page -- http://php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/125830 Del: integrated -- https://master.php.net/note/delete/125830/integrated Del: useless -- https://master.php.net/note/delete/125830/useless Del: bad code -- https://master.php.net/note/delete/125830/bad+code Del: spam -- https://master.php.net/note/delete/125830/spam Del: non-english -- https://master.php.net/note/delete/125830/non-english Del: in docs -- https://master.php.net/note/delete/125830/in+docs Del: other reasons-- https://master.php.net/note/delete/125830 Reject -- https://master.php.net/note/reject/125830 Search -- https://master.php.net/manage/user-notes.php
