note 118526 added to language.generators.syntax

If for some strange reason you need a generator that doesn't yield anything, an empty function doesn't work; the function needs a yield statement to be recognised as a generator. <?php function gndn() { } foreach(gndn() as $it) { echo 'FNORD'; } ?> But it's enough to have the yield syntactically present even if it's not reachable: <?php function gndn() { if(false) { yield; } } foreach(gndn() as $it) { echo 'FNORD'; } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 122.57.151.138 ---- Manual Page -- http://php.net/manual/en/language.generators.syntax.php Edit -- https://master.php.net/note/edit/118526 Del: integrated -- https://master.php.net/note/delete/118526/integrated Del: useless -- https://master.php.net/note/delete/118526/useless Del: bad code -- https://master.php.net/note/delete/118526/bad+code Del: spam -- https://master.php.net/note/delete/118526/spam Del: non-english -- https://master.php.net/note/delete/118526/non-english Del: in docs -- https://master.php.net/note/delete/118526/in+docs Del: other reasons-- https://master.php.net/note/delete/118526 Reject -- https://master.php.net/note/reject/118526 Search -- https://master.php.net/manage/user-notes.php
