note 118776 added to class.generator

Unlike return, yield can be used anywhere within a function so logic can flow more naturally. Take for example the following Fibonacci generator: <?php function fib($n) { $cur = 1; $prev = 0; for ($i = 0; $i < $n; $i++) { yield $cur; $temp = $cur; $cur = $prev + $cur; $prev = $temp; } } $fibs = fib(9); foreach ($fibs as $fib) { echo " " . $fib; } // prints: 1 1 2 3 5 8 13 21 34 ---- Server IP: 72.52.91.14 Probable Submitter: 162.220.76.6 ---- Manual Page -- http://php.net/manual/en/class.generator.php Edit -- https://master.php.net/note/edit/118776 Del: integrated -- https://master.php.net/note/delete/118776/integrated Del: useless -- https://master.php.net/note/delete/118776/useless Del: bad code -- https://master.php.net/note/delete/118776/bad+code Del: spam -- https://master.php.net/note/delete/118776/spam Del: non-english -- https://master.php.net/note/delete/118776/non-english Del: in docs -- https://master.php.net/note/delete/118776/in+docs Del: other reasons-- https://master.php.net/note/delete/118776 Reject -- https://master.php.net/note/reject/118776 Search -- https://master.php.net/manage/user-notes.php
