How does PHP obtain a new URL through URL access? [call Baidu Map]

How to access PHP Through URL to get a new URL [call Baidu Map] I want to perform a navigation on my mobile phone
If the URL address of the current navigation is entered into the IE address bar can be accessed normally: http://api.map.baidu.com/direction? Origin = latlng: 24.481428, 118.124813 | name: Test start point & destination = latlng: 24.503361, 118.139877 | name: Test end point & mode = driving & region = Xiamen & output = html

After the input, press enter to find that the address is changed:
Http://map.baidu.com /? L = & s = nav % 26sn % 3D1% 24% 24% 24% 2C2794316. 21% 24% 24% E6 % B5 % 8B % E8 % AF % 95% E8 % B5 % B7 % E7 % 82% B9 % 24% 24% 24% 24% 24% 26en % 3D1% 24% 24% 24% 24% 2C2796984. 18% 24% 24% E6 % B5 % 8B % E8 % AF % 95% E7 % BB % 88% E7 % 82% B9 % 24% 24% 24% 24% 24% 26sc % 3D194% 26ec % 3D194

I want to know how to use PHP to obtain a new URL based on the original URL after the request? Thank you.

Reply to discussion (solution)

The reason for transcoding is that it contains Chinese characters. I found that the IPHONE navigation page cannot be opened and is blank.
However, if a new URL is obtained after a URL request is sent, you can enable the Baidu map normally by configuring it.

So I want to write a function to handle this problem. thank you.

Original? Is the url of http://api.map.baidu.com/direction? Origin = latlng: 24.481428, 118.124813 | name: Test start point & destination = latlng: 24.503361, 118.139877 | name: Test end point & mode = driving & region = Xiamen & output = html

The new url is http://map.baidu.com /? L = & s = nav % 26sn % 3D1% 24% 24% 24% 2C2794316. 21% 24% 24% E6 % B5 % 8B % E8 % AF % 95% E8 % B5 % B7 % E7 % 82% B9 % 24% 24% 24% 24% 24% 26en % 3D1% 24% 24% 24% 24% 2C2796984. 18% 24% 24% E6 % B5 % 8B % E8 % AF % 95% E7 % BB % 88% E7 % 82% B9 % 24% 24% 24% 24% 24% 26sc % 3D194% 26ec % 3D194

Can I use a new url? ,? No ,???

So you want to get the root ?? Url? Get the new url and then use it?

This is what it means, brother. I am like using an old URL to generate a new URL.
Thank you.

Thank you for your reply.
However, I am using Sina SAE, which prompts me:
Warning: get_headers () has been disabled for security reasons in test. php on line 7


Can get_headers () be replaced by another method? Thank you.

Try.

$ Url = 'http: // api.map.baidu.com/direction? Origin = latlng: 24.481428, 118.124813 | name: Test start point & destination = latlng: 24.503361, 118.139877 | name: Test end point & 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 '';}

Powerful, bro. You got 100 points. Close the post.
Thank you.

Later, I found another one and shared it by the way.

private function getHeadersNew($url){ $ch= curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_NOBODY, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); $f=curl_exec($ch); curl_close($ch); $h=explode("\n",$f); $r=array(); foreach( $h as $t){   $rr=explode(":",$t,2);   if(count($rr)==2 ){ $r[$rr[0]]=trim($rr[1]);} } return $r; }
