How to access php via URL, get a new URL "call Baidu map"

How to access php via URL, get a new URL "call Baidu map"
I'm trying to do a little navigation on my phone.
The URL address of the current navigation can be accessed normally if it is entered into the IE Address bar: http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813|name: Test start &destination=latlng:24.503361,118.139877|name: Test End &mode=driving&region= Xiamen &output=html

After inputting, the carriage return will find that the address becomes:
http://map.baidu.com/?l=&s=nav%26sn%3D1%24%24%24%2413149737.11%2C2794316.21%24%24%E6%B5%8B%E8%AF%95%E8%B5% B7%e7%82%b9%24%24%24%24%24%24%26en%3d1%24%24%24%2413151414.05%2c2796984.18%24%24%e6%b5%8b%e8%af%95%e7%bb%88%e7 %82%b9%24%24%24%24%24%24%26sc%3d194%26ec%3d194

Want to know how to use PHP to implement the original URL, the request after the new URL? Thank you.






------Solution--------------------
The original URL is http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813
------Solution--------------------
Name: Test start &destination=latlng:24.503361,118.139877
------Solution--------------------
Name: Test End &mode=driving&region= Xiamen &output=html

The new URL is http://map.baidu.com/?l=&s=nav%26sn%3D1%24%24%24%2413149737.11%2C2794316.21%24%24%E6%B5%8B%E8%AF%95% E8%b5%b7%e7%82%b9%24%24%24%24%24%24%26en%3d1%24%24%24%2413151414.05%2c2796984.18%24%24%e6%b5%8b%e8%af%95%e7%bb %88%e7%82%b9%24%24%24%24%24%24%26sc%3d194%26ec%3d194

With the new URL can be opened, old not, right?

So you think you can get a new URL from the old URL and then use it?
------Solution--------------------
Give it a try.

$url = ' http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813
------Solution--------------------
Name: Test start &destination=latlng:24.503361,118.139877
------Solution--------------------
Name: Test End &mode=driving&region= Xiamen &output=html ';
$newurl = Getmapurl ($url);
Echo $newurl;

function Getmapurl ($url) {
    File_get_contents ($url);
    $result = $http _response_header;
    if ($result) {
        foreach ($result as $val) {
            if (substr ($val, 0,10) = = ' Location: ') {
                return Str_replace (' Location: ', ', $val);
            }
        }
    }
    Return ';
}
