Question

如果我从db表（ Mysql ）读取数据，我会将其作为返回：

[{"name":"Mobile Groups","value":1,"target":null,"alias":"mb_group","required":1,"showNull":0},
{"name":"Beta Group","value":3,"target":null,"alias":"mb_group","required":1,"showNull":0},
{"name":"Delta Group","value":4,"target":null,"alias":"mb_group","required":1,"showNull":0}]

我无法在任何地方找到这种数据类型，但那不是数组，是吗？我可以将此数据转换为数组，我需要这些数据用于我的checboxes和单选按钮，因为我将使用 foreach 来控制它，这是可能的吗？

Answer 1

$string = '[{"name":"Mobile Groups","value":1,"target":null,"alias":"mb_group","required":1,"showNull":0},
{"name":"Beta Group","value":3,"target":null,"alias":"mb_group","required":1,"showNull":0},
{"name":"Delta Group","value":4,"target":null,"alias":"mb_group","required":1,"showNull":0}]';

$array = json_decode($string);

var_dump($array);

输出

array (size=3)
  0 => 
    object(stdClass)[1]
      public 'name' => string 'Mobile Groups' (length=13)
      public 'value' => int 1
      public 'target' => null
      public 'alias' => string 'mb_group' (length=8)
      public 'required' => int 1
      public 'showNull' => int 0
  1 => 
    object(stdClass)[2]
      public 'name' => string 'Beta Group' (length=10)
      public 'value' => int 3
      public 'target' => null
      public 'alias' => string 'mb_group' (length=8)
      public 'required' => int 1
      public 'showNull' => int 0
  2 => 
    object(stdClass)[3]
      public 'name' => string 'Delta Group' (length=11)
      public 'value' => int 4
      public 'target' => null
      public 'alias' => string 'mb_group' (length=8)
      public 'required' => int 1
      public 'showNull' => int 0

此外，您可以使用TRUE参数获取数组转换对象：

$array = json_decode($string, true);

Answer 2

对我来说看起来像JSON，更具体地说是三个对象的JSON数组。

在PHP中，您应该能够json_decode()。

这是什么数据类型，参数
