How to access $array[@key] value

Question

I am working with expedia API's and its working well but I don't know how to access this special type of array key. Response is given below

$response = 
stdClass Object
(
    [@size] => 1
    [@activePropertyCount] => 144
    [city] => 1
    [@hotelId] => 12345
    [HotelSummary] => stdClass Object
        (
            [@order] => 0
            [@ubsScore] => 1074874
            [hotelId] => 151689
            [RoomRateDetailsList] => stdClass Object
                (
                    [RoomRateDetails] => stdClass Object
                        (
                            [roomTypeCode] => 195577
                            [rateCode] => 202369379
                            [maxRoomOccupancy] => 3
                            [quotedRoomOccupancy] => 2
                            [minGuestAge] => 0
                            [roomDescription] => Deluxe Room
                            [propertyAvailable] => 1
                            [propertyRestricted] => 
                            [expediaPropertyId] => 526332
                        )
                )
        )
)

I want to access the value of @hotelId under the 'city' key but I can't

I tried with both type but failed both time as

$response->hotelId
and 
$response->@hotelId

Please help me.. thank you in advance

Sorry, the response is not an array but it is an object of type stdClass. So I can't access it with $response['@hotelId'] — vikujangid

@banditpanda thank you its working but the result is not accurate as i want. It gives me 'string(5) "12345"' but I want only 12345 — vikujangid

it's just var_dump function specification use echo or print — Tobiasz

This should work for you:

(This is because you can't access a property which doesn't have a legal variable name, so you have to use curly syntax)

echo $response->{"@hotelId"};

You can read more about this in the manual: http://php.net/manual/en/language.variables.variable.php

And a quote from there:

Curly braces may also be used, to clearly delimit the property name. They are most useful when accessing values within a property that contains an array, when the property name is made of mulitple parts, or when the property name contains characters that are not otherwise valid (e.g. from json_decode() or SimpleXML).

@ankitverma Then you probably stored the output from var_dump() in your array element. Please show your output from: print_r($response["abc"]["@hotelld"]); (Best just post a pastebin link here). If you really stored the output of: var_dump() in the element I would first search for the source where you did it and change it there, otherwise you would have to use a regex, e.g. preg_match("/String$\d+$$\"(.*?)\"$/", $input). Also note that this question is actually about object properties and not array elements.
