Я хочу повторить каждый идентификатор и ИМЯ из каждого блока, но я очень новичок в json, и я всегда застреваю, когда мне нужно прочитать более одного данные. Спасибо за любую помощь.

Комментарии:

1. Пожалуйста, покажите, как объект JSON передается в переменную PHP и как он там выглядит.

2. Это недопустимый JSON. В допустимом JSON, / должно быть экранировано внутри строк .

Ответ №1:

Предполагается, что показанный вами объект JSON назначен как объект переменной JS o , и вы хотите выполнить цикл в JS:

 for (i = 0; i < o.data.length; i  ) {
    alert(
        'id = '   o.data[i].id   'n'  
        'name = '    o.data[i].name    'n'  
        'from.id = '   o.data[i].from.id   'n'  
        'from.name = '    o.data[i].from.name
    );
}

Предполагается, что показанный вами объект JSON назначен как объект в строковой переменной PHP $s :

 $aObject = json_decode($s, true);
foreach ($aObject['data'] as $i => $a) {
    echo
        'id = ' . $a['id'] . "<br />n" .
        'name = ' . $a['name'] . "<br />n" .
        'from.id = ' . $a['from']['id'] . "<br />n" .
        'from.name = ' . $a['from']['name'] . "<br /><br />nn";
}

Комментарии:

1. Упс, извините, видел только нотацию JSON, которую невозможно определить таким образом в PHP.

2. Обновил мой ответ, добавил цикл PHP.

3. Телен, превзойди меня, 1 за скорость и точность

Ответ №2:

кстати, о каких идентификаторе и имени вы говорите: внутри data или внутри data.from

Способ Javascript

 var jsondata = {"data": [{ // given string }]};

for (var i=0; i<json.data.length; i  ) {
  document.write("<hr/><b>" i "</b><br/>");
  document.write("Data ID=>"   json.data[i].id ";Data Name=> "   json.data[i].name   "<br/>");
  document.write(i "From ID: "   json.data[i].from.id ";From Name:"   json.data[i].from.name );
}

ДЕМОНСТРАЦИЯ

PHP способ

 $decodejson = json_decode($jsondata, true);
foreach ($decodejson ['data'] as $k => $v) {
echo
        'id =>' . $v['id'] . "<br />n" .
        'name => ' . $v['name'] . "<br />n" .
        'from.id =>' . $v['from']['id'] . "n" .
        'from.name => ' . $v['from']['name'] . "n";
}

1. @jurgen Спасибо 🙂 что мне нужно изменить?? я не получил u

2. Ваш код верен. Я имел в виду, что оба наших ответа были получены почти в одно и то же время (близко друг к другу). Я не являюсь носителем языка, пожалуйста, потерпите меня.
