note 124334 added to generator.send

I have found that inverse generators (using $x = yield) is a great way to handle chunked batch processing. As data is being iterated, once a specific count has been fed to the generator, it processes and resets the data. For example, you could do a batch mysql insert every 500 records. Example (note the handling of null, which you would send to the generator to handle stragglers after the previous batch) function importer() { $max = 500; $items = []; while (true) { $item = yield; if ($item !== null) { $items[] = yield; } if ($item === null || count($items) >= $max) { // do batch operations $items = []; } } } ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.54 (proxied: 64.125.67.66) ---- Manual Page -- http://php.net/manual/en/generator.send.php Edit -- https://master.php.net/note/edit/124334 Del: integrated -- https://master.php.net/note/delete/124334/integrated Del: useless -- https://master.php.net/note/delete/124334/useless Del: bad code -- https://master.php.net/note/delete/124334/bad+code Del: spam -- https://master.php.net/note/delete/124334/spam Del: non-english -- https://master.php.net/note/delete/124334/non-english Del: in docs -- https://master.php.net/note/delete/124334/in+docs Del: other reasons-- https://master.php.net/note/delete/124334 Reject -- https://master.php.net/note/reject/124334 Search -- https://master.php.net/manage/user-notes.php
