Variable $d comes from file_get_contents function to a URL.

How can I retrieve value of each element and add to an array? I can't figure it out.

推荐答案

$answer 已经可以用作数组.如果你想把它放在一个真正的数组中，你可以这样做，

The $answer can already work as an array. You can do this if you want put it in a real array,

$array = array();
foreach($answer as $k => $v) {
  $array[$k] = $v;
}
