php数据："["master":["skill_id":"1","master_number":"A","master_name":"概念设计","master_max_score":"15"]]" 如何转换成数组？现在是字符串

可以使用json_decode()函数将该字符串转换为数组。具体代码如下所示：

$str = '{"master":[{"skill_id":"1","master_number":"A","master_name":"概念设计","master_max_score":"15"}]}';
$arr = json_decode($str, true);
print_r($arr);

输出结果为：

Array
(
    [master] => Array
        (
            [0] => Array
                (
                    [skill_id] => 1
                    [master_number] => A
                    [master_name] => 概念设计
                    [master_max_score] => 15
                )

        )

)
