Combine array with same value and add other [duplicate]

PHP Snippet 1:

foreach($data as $key => $elem) {
    if (!isset($result[$elem["date"]])) {
        $result[$elem["date"]] = $elem;
    } else {
        $result[$elem["date"]]["count"] += $elem['count'];
        $result[$elem["date"]]["audio_click"] += $elem['audio_click'];
    }
}
$result = array_values($result); // optional
