【问题描述】：

我有一个如下所示的 json 对象：

"Sunday":[
        {
            "low":"00:15",
            "high":"00.45",
            "mid":["00:30"]
        },
        {
            "low":"01:15",
            "high":"02.45",
            "mid":["01:30","01:45","02:00","02:15","02:30"]
        }

    ],
    "Monday":[
        {
            "low":"00:15",
            "high":"00.45",
            "mid":["00:30"]
        },
        {
            "low":"01:15",
            "high":"02.45",
            "mid":["01:30","01:45","02:00","02:15","02:30"]
        }

    ]

我正在使用 json_decode() 方法使其成为一个数组，如下所示：

Array ( [Sunday] => Array ( [0] => Array ( [low] => 01:15 [high] => 02.45 [mid] => Array ( [0] => 01:30 [1] => 01:45 [2] => 02:00 [3] => 02:15 [4] => 02:30 ) ) [1] => Array ( [low] => 00.45 [high] => 00:30 [mid] => Array ( [0] => 01:30 [1] => 01:45 [2] => 02:00 [3] => 02:15 [4] => 02:30 ) ) ) )

我能够成功地从 mysql 获取上述数组并将其传递给 javascript，但我对如何将相同的 json 数组放回 mysql 感到困惑。

mysql 表如下所示： |ID|日|低|高|中|

请帮助我知道如何最好地解决这个问题。

谢谢

读取提供的输入数据和输出（DB表期望），为您制作了这个解决方案：

您的 JSON 输入数组：

public function arr2ins()
{
    $arr = [
        "Sunday" => [
            [
                'low' => "00:15", 
                'high' => "00.45",
                'mid' => [
                    "00:30",
                ],
            ],
            [
                'low' => "01:15", 
                'high' => "02.45",
                'mid' => [
                    "01:30",
                    "01:45",
                    "02:00",
                    "02:15",
                    "02:30",
                ],
            ],
        ],
        "Monday" => [
            [
                'low' => "00:15", 
                'high' => "00.45",
                'mid' => [
                    "00:30",
                ],
            ],
            [
                'low' => "01:15", 
                'high' => "02.45",
                'mid' => [
                    "01:30",
                    "01:45",
                    "02:00",
                    "02:15",
                    "02:30",
                ],
            ],
        ],
    ];

    $insert = array();

    foreach($arr as $k1 => $v1)
    {
        foreach($v1 as $k2 => $v2)
        {
            $insert[] = array(
                'ID' => '', 
                'Day' => $k1, 
                'Low' => $v2['low'],
                'High' => $v2['high'],
                'Mid' => is_array($v2['mid']) ? implode(',', $v2['mid']) : $v2['mid'],
            );
        }
    }

    echo '<pre>',var_dump($insert);

}
