Php 需要在数组中获取数组值

我有一个数组作为查询的结果，数组中有一个关联数组。我需要选择价值产品，即我需要从这个结果中获得

[“176”、“143”、“60”]

。 请帮我拿这个

stdClass Object ( 
    [num_rows] => 1 
    [row] => Array ( 
        [setting] => {"name":"featured","product_name":"","product":["176","143","60"],"limit":"10","width":"200","height":"200","status":"1"} 
    ) 
    [rows] => Array ( 
        [0] => Array ( 
            [setting] => {"name":"featured","product_name":"","product":["176","143","60"],"limit":"10","width":"200",
"height":"200","status":"1"} 
        ) 
    ) 
)

您不会因此得到数组。您将获得stdClass，它是一个对象。 您必须访问它的属性。这个属性是一个数组，它包含一个json编码的字符串元素，所以您必须首先对它进行解码，然后访问您感兴趣的数组键。 另外，您没有指定您感兴趣的产品数据（来自row或rows属性？是否可以有更多的行？）

---

它返回一个stdClass，根据您获取SQL资源的方法，强制它返回一个关联数组，然后您就可以通过索引获取它。顺便说一句，重新格式化您的示例以使其更具可读性。

设置

类似JSON的loos-因此请阅读

<?php

$data = new stdClass();
$data->num_rows = 1;
$data->row = [
  'setting' => '{"name":"featured","product_name":"","product":["176","143","60"],"limit":"10","width":"200","height":"200","status":"1"}',
];
$data->rows = [
  0 => [
    'setting' => '{"name":"featured","product_name":"","product":["176","143","60"],"limit":"10","width":"200","height":"200","status":"1"}'
  ]
];

// get product array from row
var_dump(json_decode($data->row['setting'])->product);

// get product array from first row of rows
var_dump(json_decode($data->rows[0]['setting'])->product);

// get product array from all rows
array_map(function(array $row) {
  var_dump(json_decode($row['setting'])->product);
}, $data->rows);

array(3) {
  [0]=>
  string(3) "176"
  [1]=>
  string(3) "143"
  [2]=>
  string(2) "60"
}
