php – 添加到数组值

我从mysql数据中获取：

$starcik_o = MysqL_query("select id, mapa, miasto, nazwa_obiektu from oferty where id = 28");
        while($data = MysqL_fetch_array($starcik_o, MysqL_ASSOC)) $punkty[] = $data;

我想在这个数组中添加另一个表,我试着这样做：

foreach ($punkty as $item)
        {
        $deserialized = unserialize($item['mapa']);
        $punkty['long'] = $deserialized['lng'];
        $punkty['lat'] = $deserialized['lat'];
        }

但它不像我想的那样工作,因为var_dump($punkty);告诉我

array(3) 
{ 
    [0]=> array(4) 
    { 
    ["id"]=> string(2) "28" 
    ["mapa"]=> string(97) "a:3:{s:3:"lat";s:17:"49.21103723075132";s:3:"lng";s:18:"22.330280542373657";s:4:"zoom";s:2:"17";}" 
    ["miasto"]=> string(5) "Cisna" 
    ["nazwa_obiektu"]=> string(44) "Cisna - noclegi u Mirosławy w Bieszczadach" 
    } 
    ["long"]=> string(18) "22.330280542373657" 
    ["lat"]=> string(17) "49.21103723075132" 
}

解决方法:

使用

foreach ($punkty as $key => $item)
        {
        $deserialized = unserialize($item['mapa']);
        $punkty[$key]['long'] = $deserialized['lng'];
        $punkty[$key]['lat'] = $deserialized['lat'];
        }
