我整个早上都在敲打我的大脑，我终于屈服于寻求帮助。

                "height": 2592,
                "alt": ""
          }
        }
      }
    }';

$data = json_decode($data, true);

我正在尝试获取所有具有等于“uri”的“键”的值

所以在这个例子中，结果将返回：

array(
   0 => 06b01b_8675350495a4472ea473f93589258f01~mv2_d_1936_2592_s_2.jpg
)

我试过使用：

array_search，array_column也试过了array_map

有人可以帮我吗？

解决方案

这个怎么样：

$matches = [];
$identifier = 'uri';
array_walk_recursive($data, function ($item, $key) use (&$matches, $identifier) {
    if ($key == $identifier) {
        return $matches[] = $item;
    }
});

print_r($matches);

Array ( [0] => 06b01b_8675350495a4472ea473f93589258f01~mv2_d_1936_2592_s_2.jpg )
