Get parameters for an interface

The interface is as follows:
Http://wthrcdn.etouch.cn/weather_mini?city= Beijing

Direct input from the browser to get the return value
But I used file_get_contents (), fopen (), and curl get no return value.
Beginners, do not know whether the use of their own problems.

$url = ' Http://wthrcdn.etouch.cn/weather_mini?city=%E5%8C%97%E4%BA%AC '; Echo gzdecode (file_get_contents ($url));
