Note Submitter: hueen ---- In addition to the previous post by Krzysztof: The above manual states that "Reference of a $value and the last array element remain even after the foreach loop", but it should also be noted that foreach does not reinitialize $value _before_ iterating. This means that if $value is a reference (of anything) before a foreach($array as $value) loop, it will remain a reference while foreach is iterating (and thus the reference's target gets overwritten with each iteration). If that foreach is run by reference though (foreach($array as &$value)), $value's original reference inherently gets dropped and it references each current $array element instead (as expected).
