Question

我有一个这样的数组：

0 => array:8 [▼
      "_id" => MongoId {#266 ▶}
      "name" => "New param"
      "default" => "900"
      "visibility" => "1"
      "type" => 1
      "only_numbers" => "1"
      "value" => "900"
      "available" => "1"
    ]

如何将此数组折叠为：

$arr["New param"] = "900";

仅限：

$arr = array(
   $a["name"] => $a["value"]
);

看起来您的数组是另一个数组的元素（顶部隐含的$arr[$a[0]['name']] = $a[0]['value'];）。所以你需要索引包含数组：

foreach ($a as $el) {
    $arr[$el['name']] = $el['value'];
}

如果要获取其他数组的所有元素，请使用循环：

$arr = array_combine(array_column($a, 'name'), array_column($a, 'value'));

或者你可以这样做：

UPDATE task 
JOIN (SELECT ts.t_id 
      FROM subtask s
      JOIN task_subtask ts ON s.s_id = ts.s_id
      GROUP BY ts.t_id
      HAVING COUNT(s.s_id) = SUM(s.done) 
      ) x
ON task.t_id = x.t_id
SET all_done = 1

如何折叠阵列？
