Or upon further examination !
But not sure how to rewrite as I didn't understand the $key purpose in the

Warning
Reference of a $value and the last array element remain even after the foreach

It is recommended to destroy it by unset().
Reference:
http://php.net/manual/en/control-structures.foreach.php
unset($value); // break the reference with the last element
