i have stored token received web service in $token, can please tell me going wrong?

looking forward response,

thank you

the problem seems use single quotation mark, want pass token var.

should be:

echo $token; curl_setopt($ch, curlopt_httpheader, array(                                                                           'content-type: application/json',                                                                                 "x-auth-token: $token"));
