                    }
                }
            }
        }
    }
}

}

这是我的php文件

 <?php
$json_file = file_get_contents('xyz.json');
$jfo = json_decode($json_file, TRUE);
foreach("tried a lot here nothing seems to work fo me")

这里我想获取一个数组中的所有金额值。我无法得到它请帮助我。

您需要多个foreach()语句来执行此操作，每个级别一个。

$amounts = [];
foreach ($jfo as $people) {
    foreach ($people as $person) {
        foreach ($person['partners'] as $partner) {
            foreach ($partner['prices'] as $price) {
                $amounts[] = $price['amount'];
            }
        }
    }
}
print_r($amounts);

输出：

Array
(
    [0] => 125
    [1] => 139
    [2] => 52
    [3] => 72
)

来自json获得特定项目的多维数组
