我想在用户元素的数组中为每个元素添加一个属性，这样它就会像这样结束
[user] => Array
(
[id] => 221418717
[id_str] => 221418717
[name] => Craig Price
[screen_name] => CraigPrice1
[location] => Glanamman
[description] => Beer & Sport!
[url] =>
[entities] => Array
***[selected] => 0***
(
[description] => Array
(
[urls] => Array
(
)
)
)
我将如何做到这一点。这就是我提出的但无济于事的原因：
$list = file_get_contents('tweets.json');
$json = json_decode($list, true);
foreach($json as $key => $val)
{
$array[$key]['selected'] = 0;
}
答案 0 :(得分：3)
使用$json代替$array：
$json[$key]['selected'] = 0;
