A curious problem here and I'm sure the answer is staring me right in the face but I cannot see it.
I have called some data from Ebays api and I have recieved a json file in response.
To help me debug an potential errors, I use var_dump() to see what the data looks like before and after it has been decoded but in this case when i use var_dump() after i have used json_decode() it comes up NULL.
I have used this code for two other sites and I cannot see why this is has crept in. Here is the code I am using:
$url = "http://svcs.ebay.co.uk/services/search/FindingService/v1?SECURITY-APPNAME=(App Id)&OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=JSON&callback=_cb_findItemsByKeywords&GLOBAL-ID=EBAY-GB&REST-PAYLOAD&keywords=Iphone&paginationInput.entriesPerPage=2";
$headers = array( "Content-type: application/json;charset=\"utf-8\"", "Accept: text/xml", "Cache-Control: no-cache", "Pragma: no-cache", "SOAPAction: \"run\"");
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HTTPGET, true);
curl_setopt($cURL, CURLOPT_HTTPHEADER, $headers);
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($cURL);
$json=json_decode($result, true);
echo"<br>result in json <br>";
var_dump($result);
echo "<br><br> Json Decoded <br>";
var_dump($json);
curl_close($cURL);
the result is:
result in json

Json Decoded
NULL
Any ideas where i have gone wrong with this?
Your JSON contains /**/_cb_findItemsByKeywords(, which malformes the JSON string. json_decode returns NULL if the string cannot be parsed.
