php中$_POST[]取不到值怎么解决？
1、在php.ini 配置文件中，确保enable_post_data_reading值为On，这样才会自动将 POST 数据填入 $_POST 数组中。
2、检查头信息content-type是不是为“content-type:application/x-www-form-urlencoded" 这种传输是以表单的方式提交数据php使用$_POST方式接受。
如果头信息content-type为“content-type:application/json"这种传输是以json方式提交数据，php需要使用file_get_contents("php://input")获取输入流的方式接受
3、确保使用本地Apache服务器
例：如果用phpstorm自带的服务器，则$_POST不能接收form传的数据，不知道原因
