    Всем привет!

    Имеется такой массив:
    PHP:

    Array
    (
        [    0] => Array
            (
                [    0] => {"id":19409,"name":"\\u0420\\u043e\\u0441\\u043d\\u043e\\u0441\\u043a\\u043e\\u043d\\u043e\\u0441","dir":"n","expansion_stage":3,"x":788,"y":648,"ox":629,"oy":170,"offer":"stone","demand":"wood","mood":100,"relation_status":1,"ratio":1.25,"loot":1342173457,"lootable_human":"13.07.12 \\u0432 13:57","looted":1342173157}

                [    3] => {"id":19412,"name":"\\u0422\\u0430\\u0445\\u0438\\u0433\\u0430","dir":"n","expansion_stage":3,"x":788,"y":648,"ox":694,"oy":296,"offer":"stone","demand":"wood","mood":100,"relation_status":0,"ratio":1.25}

                [    5] => {"id":19414,"name":"\\u0414\\u043e\\u043d\\u043e\\u0441\\u0433\\u0430\\u0444\\u043e\\u0441","dir":"n","expansion_stage":3,"x":788,"y":648,"ox":228,"oy":265,"offer":"wood","demand":"iron","mood":100,"relation_status":1,"ratio":1.25,"loot":1342173456,"lootable_human":"13.07.12 \\u0432 13:57","looted":1342173156}
                [    6] => {"id":19415,"name":"\\u041d\\u044d\\u0439\\u0440\\u043e\\u0441","dir":"n","expansion_stage":3,"x":788,"y":648,"ox":589,"oy":365,"offer":"iron","demand":"wood","mood":100,"relation_status":0,"ratio":1.25}
                [    7] => {"id":19416,"name":"\\u0421\\u0442\\u0440\\u0430\\u0439\\u043d\\u043e\\u0441\\u043a\\u043e\\u0443\\u0441","dir":"n","expansion_stage":3,"x":788,"y":648,"ox":772,"oy":274,"offer":"stone","demand":"wood","mood":100,"relation_status":0,"ratio":1.25}
            )

    )
    Нужно все его значения прогнать через json_decode

    Понимаю, что нужно использовать foreach... но как правильно написать не знаю... Для каждого элемента в отдельности json_decode срабатывает...

    Ну и пиши типа
    PHP:
    foreach($array[0] as $item)
    {
      echo     json_decode($item);
    }

    Тогда выполни var_dump($твой_массив) и покажи результат

          }
    }
     
    Может я вообще не тем путем пошел...
    Мне нужно из этого массива выбрать значения Id, name и relation_status, и положить их в переменные...

    А, ну да, json_decode не строку возвращает. Посмотри документацию на php.net, там описано как из результата таскать нужные параметры.
    Сам по себе цикл нормальный

    На сколько я знаю, брать значения можно только с помощью json_decode. Или преобразовать массив в строку и оттуда парсить значения (но это не желательно)...

    Может есть другие варианты?

    Чем не устраивает вариант, который написал Kaimi вторым постом в теме?
    Хочешь модифицировать исходный массив на лету?
    Почему не почитал мою ссылку, которую я давал на php.net про json_decode? Второй параметр со значением true указывает, что надо преобразовать в массив ассоциативный а не класс.
    PHP:
    for ($i = 0; $i < count($yourArray[0]); $i++) {
    $yourArray[0][$i] = json_decode($yourArray[0][i], true);
    }
    print_r($yourArray);
    print(    $yourArray[0][2]["name"])
    В чём проблема то у тебя я никак не пойму?

    Спасибо Melfis. Теперь все получилось... Просто если использовать foreach, я получаю массив с одинаковыми ключами, и не могу разобраться как далее использовать полученные значения... А через цикл все супер... Спасибо!

    Ну если проблема была только в этом, то чтобы знать
    foreach($array as $key=>$value) {}
