PHP-function each() has been deprecated (ZF2)

[alexgit2k]

The PHP-function each() has been deprecated as of PHP 7.2.0 (https://wiki.php.net/rfc/deprecations_php_7_2#each), but is still used in ZF 2.4:

library/Zend/XmlRpc/AbstractValue.php: list($type, $value) = each($xmlAsArray);
library/Zend/XmlRpc/AbstractValue.php: list($type, $value) = each($namespaceXml);

tests/ZendTest/Db/Sql/Platform/Mysql/MysqlTest.php: list($type, $decorator) = each($decorators);
tests/ZendTest/Db/Sql/Platform/SqlServer/SqlServerTest.php: list($type, $decorator) = each($decorators);
tests/ZendTest/Form/View/Helper/FormSelectTest.php: list($value, $label) = each($options);
tests/ZendTest/ServiceManager/TestAsset/FooInitializer.php: list($key, $value) = each($this->var);
tests/ZendTest/XmlRpc/RequestTest.php: while (list(, $node) = each($result)) {
tests/ZendTest/XmlRpc/RequestTest.php: while (list(, $node) = each($result)) {

So each() should be replaced by foreach() which is also 10 times faster.
