Question

I am having issues with this code

This is my PHP that worked with other projects…

$gas = file_get_contents('http://api.mygasfeed.com/stations/loadbygeo/47.9494949/120.23423432/reg|mid|pre|diesel/'. $api . '.json?callback=?');



$json_output = json_decode(utf8_decode($gas));

$location= $json_output->geoLocation->city_id;

This is the JSON result

?({"status":{"error":"NO","code":200,"description":"none","message":"Request    ok"},"geoLocation":{"city_id":"13123","city_long":"Hulunber","region_short":"Nei Mongol","region_long":"Nei Mongol","country_long":"China","country_id":"49","region_id":"6010"},"stations":[]})

This code is returning a blank result.

You need to remove the ?( and the ). See WP:JSONP.

One could use substr() for that, or better yet a regex to assert and remove only the desired garbage:

$json = preg_replace("/ ^[?\w(]+ | [)]+\s*$ /x", "", $jsonp);

Would remove arbitrary callbackFnNames( but also your strange ?( pseudo function call.
