Previous Comments: ------------------------------------------------------------------------ [2014-10-13 03:13:07] pegasus at vaultwiki dot org Description: ------------ Historically, foreach ($arr AS $val) has acted on a copy of $arr, in order to prevent issues if $arr entries are modified after the loop has already begun iterating. If the current value was desired, historically for or while loops were used instead. However, in Master, it appears that $arr always refers to the current value of $arr. This is in contradiction to the historical behavior. If entries are added inside the loop, foreach will keep going for the new entries. If existing entries are otherwise modified, the $val corresponds to the updated entry rather than the $val when the loop began. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68215&edit=1
