CallbackIterator
CallbackIterator
allows to simulate yield
feature from PHP 5.5.
PHP >= 5.5
<?php function getAllFromDatabase($tableName) { $page = 0; $perPage = 1000; while ($rows = Db::getRows($tableName, $page, $perPage)) { foreach ($rows as $row) { yield $row; } $page++; } }
PHP < 5.5
<?php use Awesomite\Iterators\CallbackIterator; function getAllFromDatabase($tableName) { $page = 0; $perPage = 1000; $rows = []; return new CallbackIterator(function () use (&$rows, $tableName, &$page, $perPage) { if (!$rows) { $rows = Db::getRows($tableName, $page, $perPage); $page++; } if ($rows) { return array_shift($rows); } CallbackIterator::stopIterate(); }); }
