Following code produces warning constantly. class DeliveryTariffs extends BaseActiveRecord { public static function foo($arg1, $arg2 = null) { $a = self::someMethod(); $b = []; foreach ($a as $c) { foreach ($b as $d => $e) { if (count(array_intersect($e['f'], $j['f'])) / min(count($e['f']), count($j['f'])) > 0.5) { $b[$d]['g'][$h] = $j['g'][$h]; $i = true; break; } } if (!$i) { $b[] = $j; } } return $b; } } ------------------------------------------------------------------------ [2017-12-04 02:01:12] anatoly dot pashin at gmail dot com Laruence, I know problem is not in YiiBase.php :) it tries to include SpDelivery.php, which I can't post here. If you agree to not share it, I can email it to you privately. I can't determine which part of code in SpDelivery.php causes issue, because error goes away from time to time when I try to edit that file. So I change any line, error gone. I change another one and it's returned. About file acm at tweakers dot net posted: I can't reproduce it from cli (because opcache is disabled in cli). I see 'Narrowing occurred during type inference' error message when I try to open it from webroot through php-fpm. But when I press f5 to refresh page, error is gone and script is executed successfully.

After stripping a class of pretty much all its functionality, we ended with this below php code. Note, the below code is actually not useful anymore. But just running 'php filename.php' triggers this warning: PHP Warning: Narrowing occurred during type inference. Please file a bug report on bugs.php.net in Unknown on line 0 <?php class ReactionRatingService { public function calculateBoostPoints() { while ($reaction = $reactions) { $reactionRatings = $this->validFunction(); $totalWeight = 0; $runningScore = 0; $queue = []; foreach ($reactionRatings as $ratingData) { if ($runningScore != $reaction['Score']) { if ( ! $ratingData['BoostEarned']) { $queue[] = $ratingData['UserID']; } } else { foreach ($queue as $userId) { $userBoostPointsRecalculate[$userId][] = $reaction['ID']; } } $totalWeight += $ratingData['Weight']; } } } } ------------------------------------------------------------------------ [2017-12-01 10:07:34] laruence@php.net the error seems not in YiiBase.php but the file which is trying to include in line 421 could you please try to figure out which file it was trying to include? thanks ------------------------------------------------------------------------ [2017-12-01 02:03:00] anatoly dot pashin at gmail dot com Description: ------------ Today we updated php to 7.1.12 and saw some errors during deploy. Deploy algo: 1. get new files in /www/versions/795.17 directory 2. change symbolic link so it points to it 3. call php-fpm reload. Error is thrown for some requests after 1-2 minute after reload. You can see source of YiiBase.php at https://github.com/yiisoft/yii/blob/master/framework/YiiBase.php Please tell me email which I can send SpDelivery.php privately.
