How do I json_decode() this?

How can I json_decode() result of file_get_contents?

Here is my code. 

$resp = file_get_contents('https://auth.login.yahoo.co.jp/yconnect/v1/token', false, $context);

echo "check1 <br />";
var_dump($resp);

$json = json_decode($resp);

echo "check2 <br />";
var_dump($json);
echo $json['access_token'];

The result is here

check1
string(744) "{"access_token":"j9MqiEM.lKjepCGMFdKufPw1UBK_gAlG6qFxvMxHJwbopXfo9LpLUyT1z.YxwFBSydvVSMOqzVI4fX_ZVLVROlNf7ARr08s2tkFMb5_TNq.wp1MmoQm3wJaqF9gxpeQbEz4GYuGJSbDKJTw8LA_XoBNcEbL0ZDeozFEgYxII8gqi_Nfi7UhM5bd7gqV6Sp17rCECQAauZj_jJa6jyADS3me3UYxIKJB2tCJpRM.xCzVhjRWEZPqNiUI5NikXRANrSiTyn_6Z72u2ptW3vnK918TqpPBAdj.P1O5uJAZgKEmLMZLSBEIWIEOUPTJaSvI3qxxk1ItXI_5sZDAQuw.86R3eaSIolGHqWTvpLk3WqnqBvtk6w6qIVcZgJrTFxnjx_x1ijJhKACcnY.jYp6kpxMihe8hOrTEyVj4Swhmq4RUWDhAfIQDNNju5dJCqW82QyYNCQdf0IMW7uIRSvHK1FmTGrEWMv4tpojLtJEf5vnKaDbrxZ0.AB9OSRwhzMkUYkgbiEVCwqyxCy_oEQBB0uVuAL8fOYidPrqv8m.A29j7S9d3Cb7DFh7pQJJGkLzljcC4VkEZADLiPnq_aLZuy0ehb_aTLBoHZ0IUL","token_type":"bearer","expires_in":"3600","refresh_token":"ABrQBFdlHzed4sc.aHygqG0faENua5L865UMVglio2hkbIJAnbY-"}"


'check1' is there and token value is result of var_dump($resp); but 'check2' not working.
So I think $json = json_decode($resp); is fail.

How do I decode this?

Thanks.

This is encoding issue. You have BOM in your response that is not shown by var_dump but is not properly treated by json_encode.

If you try to do next:

$s = "\xEF\xBB\xBF".'{"access_token":"j9MqiEM.lKjepCGMFdKufPw1UBK_gAlG6qFxvMxHJwbopXfo9LpLUyT1z.YxwFBSydvVSMOqzVI4fX_ZVLVROlNf7ARr08s2tkFMb5_TNq.wp1MmoQm3wJaqF9gxpeQbEz4GYuGJSbDKJTw8LA_XoBNcE$

var_dump($s);
var_dump(json_decode($s));

You will get exact same result as in your response.

You can play around with headers to make sure that you are using utf-8 encoding during request or you can get rid of BOM by:

$bomBinString = pack('H*','EFBBBF');
$s = preg_replace("/^$bomBinString/", '', $s);
