You need to split the two month elements into two single objects, otherwise you will have duplicate keys date & Content.

The following code does what you expect:

// $input contains the input json string
$json = json_decode($input, true);
$outputArray = array('news' => array());

foreach($json['news'] as $news) {
    foreach($news as $month => $entries) {
        $monthNews = array(
            'date' => $month,
            'Content' => array()
        );  

        foreach($entries as $entry) {
            $monthNews['Content'][] = $entry;
        }

        $outputArray['news'][] = $monthNews;
    }
}

echo json_encode($outputArray);
