php url map access transfer

我是想在手机微信上进行一段导航
当前导航的URL地址如果录入到IE地址栏中是能正常访问的：http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813|name:测试起点&destination=latlng:24.503361,118.139877|name:测试终点&mode=driving®ion=厦门&output=html

录入后，回车会发现地址变成了：
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

想知道如果用PHP如何实现根据原来的URL，请求后得到新的URL？谢谢。

转码的原因是上面带中文的，我发现微信里,IPHONE导航页面打不开，是空白的。
但是如果通过URL请求后，得到的新URL，配置在微信里是可以正常打开百度地图的。

所以我想写一个函数来处理这个，求教高手，谢谢。

原?的url是http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813|name:测试起点&destination=latlng:24.503361,118.139877|name:测试终点&mode=driving®ion=厦门&output=html

新的url是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

用新的url就可以打?了，?的不行，??？

所以你想可以根??url?取新url然後使用？

兄弟，是这个意思。我就像用旧的URL产生新的URL。
多谢啊。

兄弟，感谢回复。
不过我用的是新浪SAE,里面提示我：
Warning: get_headers() has been disabled for security reasons in test.php on line 7

get_headers() 还能有别的办法替换么？谢谢。
