json to php (server) possible and how?

Basically i want this json output to be transferred to my 开发者_Go百科server/php.

i try this

$url="http://maps.google.com/maps/nav?q=from:9500 wil to:3000 bern";
$conte = file_get_contents($url);
echo $conte;

the json is not echo, how can i save the output to my server?

You need to urlencode the GET parameters:

echo file_get_contents('http://maps.google.com/maps/nav?q=from:9500%20wil%20to:3000%20bern');

How do you want to save it? As a file?

If you can open via file_get_contents(), then URL opening for fopen() wrappers is on.

Then you can just do...

$url = 'http://maps.google.com/maps/nav?q=from:9500 wil to:3000 bern';

$content = file_get_contents($url);

file_put_contents('google-map-json.txt', $content);

You can get that into a usable object in PHP with json_decode().

You may want to do that if you want to save it to your database.

If you don't want to overwrite the file each time, you could generate a random hash of the response for the filename, or something similar.

Update

sorry my bad. i know how to save file. but the json is not even echoed through file_get_contents.

You may not have URL fopen() wrappers enabled.

You can find out by running this...

var_dump(ini_get('allow_url_fopen'));

If it is disabled, and you can't or don't want to turn it on, you can use cURL (if you have that library installed).

Update

When I tried to access the page via file_get_contents(), I got...

HTTP/1.0 400 Bad Request

You may need to use cURL, and mimic a browser (user agent etc).

Or you can set

ini_set('user_agent', 'Mozilla or something');

And then use file_get_contents().

Update

I tried with cURL too, and it didn't work :(

I think the next step is to examine all the headers your browser sends (when it works), and then send the equivalent via cURL.

Update

I noticed the Markdown editor wasn't liking the URL (see my OP's edit), and it dawned me - urlencode() the GET params!

You can write the data to a file using PHP's IO functions

$fp = fopen('data.txt', 'a');
fwrite($fp, $conte);
fclose($fp);

You can use json_decode to parse the data from the file_get_contents() variable. (I would personally use cURL instead of file_get_contents()).
